PLEASE EVERYONE READ THIS--- (people think they break, they work).

EDIT: Hey everyone, PLEASE read this if you're buying these. I thought mine were broken out of the box like so many others. For whatever reason I decided to actually call the manufacturer or in my case the distributor Nautilus (Amazon has a button that says get product support). I was frustrated and ABOUT to just return them, but they actually taught me that them locking up out of the box is a safety feature. They don't tell you this, they should, I have no idea why, but I went through a few minute unlocking process and now they seem to work great. I'm actually happy now. Essentially you turn them upside down with all parts attached to the base, smack the base with your hand and turn them to 5lbs, after smacking upside down they should release. Take the plates out after pressing a hidden release button on the bottom of the dumbbell, inspect, and place the plates back in the base. Place the handle back in the base and test each weight. It worked for me. Yes, it's plastic inside but that is some sturdy plastic I honestly suspect it should work for a good amount of time and apparently they come with a 2 year parts warranty.

If you wouldn't mind, upvote this to save time and frustration from all the others who thought it was broken out of the box. The distributors number is 1-800-605-3369, they answered after about a 4 minute hold with me.

Below is my old review that is no longer relevant. They really need some unlock instructions in the box. I've adjusted to 3 stars because of the lack of instructions lol.

OLD REVIEW: I'm a smart user and a gym user, so this isn't user error. I've never owned weights like these, I'll probably still buy some just to save space but unfortunately these ones don't work, straight out of the box which surprised me because I assume Bowflex is a good reputable name. I'm just getting on now to contact Amazon on fixing this. I've had probably 6-7 friends come over who thought they could get it to work but nope, they all realized it's actually not working either. Only one of the dumbbells doesn't work, the other one does like half the time. We lined the numbers up correctly and everything. Come to think of it, the fact that both of these are either partly faulty or completely faulty makes me think it's a bad batch or this isn't a good brand for these.

Poor plastic product design - don't waste your money.

I was really pleased with these Dumbbells initially - simple to use and compact for a quick home workout. As you can see from the photos, they were well taken care of and used exclusively on soft carpet, not concrete. I never threw the weights or slammed them after a set, so not heavy use or abuse. Unfortunately, the mechanism that holds the weight on the handle is plastic. In less than 2 years, it somehow broke on both of my weights. It is amazing that Bowflex would use cheap plastic to hold the weights in place. After calling customer service - she was very nice - we tried to work on a resolution, but they would not honor the warranty. To replace the part was $56/each (I needed 2) plus shipping..of a weight. I would be in for more than half the cost of a new set to fix the defective piece of plastic....no, thanks. For this price point, I would have hoped for a better product design and Bowflex to repair/replace a defective product. My advice - pick another weight that will last.

Huge Space Saving Value.

Got this set for my daughter who is a nursing student and wanting to keep in shape. I've had the 1090s for years and really like them. The 552's are smaller, easier to use and perfect for women.

You just have to get use to the longer shaft required to accomodate the heavier pounds. They are not that much longer, but they are longer and require an adjustment when using them.

The 552s are easy to pull out, REALLY easy to change weights---(nice smooth dial in), and very comfortable to use. Nice grip...(.the 90s have a killer knurl in them)

...... Don't drop them....these are NOT gym quality, but home quality. Take care of them and they'll last you for years on end. Small footprint, these are really good for women, maybe not so much for men as 52 lbs. is really not enough weight for most men after a few months.. (Especially for one arm rows)..... That's where the 90s come in.

I've even thought about buying a set of these for myself they are so nice to use, but that would be overkill,lol....I like the smaller handles over the 90s but it's been 6 years now that I've been using them.

You get use to them and they are perfect for 99% of all exercises you'll ever do. HIGHLY RECOMMENDED!
