FEIERDUN DS2 Honest Review: Pros, Cons and Who It Is For

I'll be honest with you: I bought the FEIERDUN DS2 because I was tired of tripping over equipment in my basement. I'm 66, I've been lifting at home for about five years, and before this set arrived, my corner of the basement held a mismatched collection of cheap dumbbells, a curl bar, and a kettlebell that spent most of its time holding a drop cloth in place. The FEIERDUN DS2 promised to replace most of that. It did. But there are a few things I wish somebody had told me before I ordered it, and that's what this review is for.

A quick word about who I am, so you can weigh my opinion. I'm a retired high school shop teacher, I live outside Reading, Pennsylvania, and I started lifting at 61 after I struggled to lift a bag of mulch and then couldn't get up off the floor after playing with my grandkids. That was the moment. I've trained three or four mornings a week ever since, in a corner of my basement next to my workbench. I have a stiff left knee from decades on concrete shop floors, and my right shoulder complains when I press overhead, so I train around both. I'm not a coach and I'm not a doctor. Check with yours before you start anything.

Before I ordered it, I went back and forth for a couple of weeks. I looked at fixed dumbbells, which are simple and reliable but eat up a whole rack if you want a real range of weights. I looked at other adjustable sets too. What kept bringing me back to the FEIERDUN was the 5-in-1 idea: one box, five tools, no separate purchases. I'm a practical man, and that math made sense to me.

How I've Used It

My routine is simple, because simple is what survives. Three or four mornings a week, I walk down to the basement, put a rubber mat down next to the workbench, and work through a circuit: some kind of squat or lunge, a press or a row, a curl, and something for my core. The FEIERDUN DS2 handles all of it. I use it as a pair of dumbbells for most exercises, I connect the two handles with the included connector for rows, and I've used the plates as push-up stands when my wrists complain.

The set is listed at 20, 30, 40, 45, 70, and 90 pounds, and the plates detach so you can run lighter or heavier depending on the exercise. For a man my age, that range covers everything I need. I do most of my upper body work in the middle of the range and save the top end for lower body days. My wife Carol has used it too, running it much lighter, and the fact that one set works for both of us is the main reason it stayed in the basement instead of going to a yard sale.

One thing I want to be clear about: I don't switch modes in the middle of a workout. The 5-in-1 claim is real, but changing from dumbbells to the barbell setup takes a few minutes, and I'd rather spend that time lifting. I decide the night before what I'm doing, set it up in the morning, and leave it alone until I'm done.

What Nobody Tells You Before You Buy

Here's the honest part, and it's why I wanted to write this. The FEIERDUN DS2 is a genuinely good set, but it's not a perfect one, and there are a few things I think everybody should know before they click buy.

First, the dumbbells are long. The listing gives the length at 25.59 inches, and that's not a typo. A standard dumbbell is shorter, and this one feels different in your hands. You need a little more room to move, and exercises like a curl have a slightly different feel because the weight sits farther from your hands. It took me a couple of sessions to get used to it. I don't mind it now, but I'm glad I knew going in.

Second, the plates are plastic, not iron. The listing explains that they're integrally molded from high-density iron sand, not loose river sand, and the outside is plastic. That has real upsides: they're quieter than iron, they don't scar the floor, and they don't rust in a damp basement. It also means you should not drop them. I don't drop any dumbbell, but I'm extra careful with these, because a hard corner hit on a plastic plate is not something I want to test.

Third, the weight steps are wider than you might expect. The set configures at 20, 30, 40, 45, 70, and 90 pounds, and that jump from 45 to 70 is a big one. For a younger lifter, that's fine. For a 66-year-old doing curls, a 25-pound jump is not something you just step up to. I work around it by using the middle weights for most exercises and being patient with progress, but if you're the kind of person who needs to add two and a half pounds at a time, this set will frustrate you.

Fourth, the 5-in-1 versatility comes with a time cost. The connector turns the two dumbbells into a barbell, the plates become kettlebells and push-up stands, and there's a foam pad for when you want the bar across your neck. All of that works. But you won't flip between modes mid-workout, because it takes a few minutes to take plates off, move them, and put everything back together. Plan your session ahead and it's a non-issue. Expect to improvise and it'll annoy you.

Fifth, and maybe most important: the barbell mode is not a real barbell. It's two dumbbells joined by a connector, which means the weight sits in two lumps instead of spread along a bar. For rows and light squats, that's fine. But it's not the same as a proper barbell, and if you expect that, you'll be disappointed. I wasn't, because I read the listing carefully, but I've seen enough reviews to know some people are.

How It's Held Up Over Years of Mornings

I've had this set for years now, and I'll tell you what has surprised me. The plates are still in good shape. The iron sand is molded in, so there's no loose sand sloshing around, no leaking, and no strange sounds when I set them down. The rubber handles still feel solid, and the medium grip with a 1-inch diameter suits my hands fine.

The connector itself has held up as well. I've used it two or three times a week for years, mostly for rows and squats, and it still fits the handles the way it did on day one. I don't leave it assembled between workouts, and I think that helps. Taking it apart and putting it back together is part of my routine now, and it takes less than a minute.

The foam pad has held up too. It's listed as a 15 by 430 millimeter pad of high-density foam wrapped around a 5 millimeter steel core, curved to fit your neck. I use it when I put the connector across my back for squats, and it's still plush and comfortable. It also wipes down easily, which matters in a basement that isn't climate controlled.

Are there things I'd change? Sure. I'd love smaller weight steps. I'd love a shorter dumbbell. And I'd love solid iron plates, even though I know they'd be heavier to handle and harder on the floor. But nothing has broken, nothing has worn out, and nothing has made me want to replace it. For what it is, it's been a workhorse.

The Exercises I Actually Do With It

In case it helps, here's what a typical morning looks like. I start with squats, using the connector with the foam pad across my shoulders, keeping the weight in the middle of the range because of my knee. Then I do rows with the same setup. Then I switch to the dumbbells for a press, and I keep that light because my right shoulder complains overhead. I finish with curls and some core work, and twice a week I add push-ups with the plates set up as stands.

I've also used the kettlebell mode for swings, keeping it light and slow so it doesn't punish my lower back. Is it exactly the same as a real kettlebell? No. But for someone who doesn't want a fifth piece of equipment in the basement, it's close enough, and it's one more reason this set earns its place.

The point is that one set, in one corner of a basement, covers a full-body routine for a man in his sixties. The listing even lists the target use as the whole body, and that matches my experience. I don't need a gym membership, I don't need a rack of dumbbells, and I don't need a spotter. I walk downstairs, I lift, I walk back up. That's the whole pitch, and it's an honest one.

Safety Notes for Lifters Over 60

I'm not a doctor, and I'm not going to give you medical advice. What I will do is tell you what I do, and let you and your doctor decide. I checked with mine before I started lifting at 61, and I've checked again when things changed. I warm up with light movement before I touch the weights, I keep the weight where I can control it, and I stop when something hurts in a way that isn't just muscle fatigue.

With this specific set, I have two extra rules. I never drop the plates, because the plastic shells aren't made for that. And I give myself room, because a 25.59-inch dumbbell needs more clearance than a short one, especially in a tight corner. Both rules are just common sense, but common sense is easier to remember when somebody says it out loud.

My stiff left knee means I keep squats in the middle of the weight range, and my right shoulder means I press light and stop at the first sign of pain. That's not advice, that's just what I do. Your body is different, and your doctor knows more about it than I do.

Nothing has broken, nothing has worn out, and nothing has made me want to replace it. For what it is, it's been a workhorse.

Who This Is For

This set is for someone who wants a real home gym without turning a room into one. It's for the person in their sixties who wants to lift three or four mornings a week, who needs a range of weights from light to heavy, and who doesn't want to buy five separate pieces of equipment. It's for people like me, training in a corner of a basement, who value simplicity over perfection.

It's also for couples, because one set covers a wide range. My wife Carol and I both use it, at very different weights, and we don't need a second set. If you're starting out and your doctor clears you, this gives you room to grow for years without outgrowing it.

Who Should Skip It

If you need to add weight in tiny increments, this set will frustrate you. The listed steps are 20, 30, 40, 45, 70, and 90 pounds, and that's a wide ladder. If you're a competitive lifter who needs solid iron plates and precise jumps, buy fixed dumbbells. If you plan to drop weights between sets, buy rubber-coated hex dumbbells instead, because these plastic plates aren't made for that. And if you hate the idea of spending a few minutes changing configurations, you'd rather have dedicated equipment.

And if you already own a full set of fixed dumbbells, you don't need this. The FEIERDUN DS2 is a space saver, not a replacement for equipment you already use. It earns its keep when it replaces five tools, not when it sits next to five tools you already own.

None of that makes the FEIERDUN DS2 a bad set. It makes it an honest tool with honest limits, and knowing those limits before you buy is the whole point of this review.

Here's my bottom line after all these years: the FEIERDUN DS2 is not the perfect piece of equipment, because that doesn't exist. It's a practical one. It does what it says, it has held up, and it lets a 66-year-old retired shop teacher stay strong without leaving his house. I'd buy it again. If this one ever wears out, I'll replace it with the same model. That's the truth.
