FitRx Adjustable Dumbbells 2-Pack, 25lb SmartBell Dumbbell Set with 9-in-1 Quick-Select Weights, 2.5lb Increments for Home Gym

READ WARNING..... These weights are very VERY dangerous. Be warned, these weights will fall off while working out. I saw in the reviews that these weights fall off, but decided to buy anyway. When I first got them, no, they didn't fall off, but after using them for a week or two, now I have to shim the weights to make them stay on, or I would need stitches or knocked out. Unfortunately, the box has been throwed away, so returning them is a no.... FitRx most have good lawyers.... hahaha hahaha

Great Price, Fast shipping, Arrived well packed and in Perfect condition. Just wanted to share a few thoughts. I read the Best and the Worst reviews on these "Adjustable Dumbbells". I wanted a set that would work as intended and meet my Needs to have a quick and easy way to change the weight I was going to choose, by the exercise I was doing next. Honestly, I was a wee bit concerned that I might experience the plates falling of the handles, as some folks shared in their reviews. So, I was very careful and deliberate to really look them over when I received the two dumbbells. What I learned in that "inspection" is that the Weight adjustment happens ONLY when the Dumbbells are in the black plastic trays. There are some small silver metal detent pieces that are part of the cradle bases. The Dumbbells also have what appear to be white Nylon "buttons" that are depressed when the Dumbbells are in their cradles. The detents depressing the white buttons allow you to twist the grip handles to adjust the weight level you want, by rotating the grip handles. Those "buttons" are spring loaded and IF they aren't functioning properly, the locking mechanism for the individual plates may not be correctly locked in position. I pressed each of the "white buttons" with my index finger to check their movement and alignment at the base/end of each dumbbell's handle. A couple of them seemed like they were not moving smoothly in their location. I grabbed my spray can of Silicon Spray and gave each white button a small shot of Silicon. Then I depressed the "buttons" with my finger, in and out to make sure their travel within the handle base was uninhibited. A couple of them were a little "resistant" to a smooth operation, so I continued to depress and release those white buttons until they moved smoothly in their positions. With those Buttons functioning properly, I moved on to using the selection process of the various weights. The other thing I noticed was that IF the dumbbells weren't properly "nested" in the cradle base, the grip handles didn't rotate smoothly. I found that the Dumbbells needed to be seated properly in the base for the activation of the detents to disengage correctly. All it took to "free up" the ability to rotate the handles was to push down lightly on those handles, to fully engage to the detent locks, allowing the Grip handles to rotate easily in the cradles. My third thought was that to minimize the potential of a weight plate to fall out, I've chosen to mindfully rotate and use the Dumbbells with the RED FITRx - SmartBell "labels" facing Down whenever possible. That may be totally unnecessary. However, having the U-SHAPE of the weight plates completely under the forces of gravity and contained by the bar design seems to be an extra level of performance of the adjustability design. Now I Love 'Em!

Easy to change the desired weight. My purchase included two sets of dumbbells for a great price. I bought these for my husband, who is very pleased with them. He says that the people who had complaints in their reviews just weren't using them correctly. Great value for the price, which was about a third of what I would've paid for a well-known brand.

My wife and granted she is small/petite just couldn't get used to these; They were too big and bulky and weight switching isn't always smooth and easy-they sometimes get stuck. Also, using in-between weights looks and feels kind of clunky. Great idea...just doesn't work too well. These might be nit-picky things and definitely not discouraging trying them out. Just didn't work for us.

These work exactly as they're supposed to….easily change weights with the twist of the grip. They start at 5 lbs and increase by 2.5 lb increments, which makes it much easier to work your way up. I'm 73 years old and these are great for me…if you can handle working with 5 lbs, I highly recommend them.

These could be awesome. There's a couple of issues that hold them back. Hopefully they can be fixed and the next generation will be perfect. Issue 1- they stick in the base. They can be difficult to line up correctly and one side may set while the other side does not. At least once per session I have to step on the base and pull one side free and try again. It seems to be the worst when all 25 lbs are out. Issue 2- they fall off the dumbbell. Several times now a plate has fallen off. Thankfully none have hit me but one did fly off and hit my tablet. Knocked it off the bench and onto the floor. Screen protector saved it. I don't use them over my body anymore, no skull crushers or presses over the body. I use my traditional dumbbells for those now. I'm still glad I have them. For the price they are worth it. I'd just recommend being very careful with them so you don't get injured.

I've been using these weights for roughly 2 weeks now. A few days in one of the weights fell off of the dumbbell when I picked it up. I continued to use them hoping it was somehow an error on my end. This morning it happened again while I was doing shoulder presses, and this time almost fell on my head. I immediately put them away and will unfortunately be returning. I'm so disappointed, I was really excited about this set!

These are large, long, but very easy to switch between weight amounts, and the length so far doesn't hinder movements. I like the 2.5 lb increments. The turn and locking mechanism work perfectly. I like not having a bunch of weights around to stub my toe on, lol! Very happy with these so far. We'll have to see how they hold up over time.

I am really enjoying this customizable weight set in my home gym. For one, it reduced all the bulk of individual weights and is equally good in performance with all customizable weights. Easy to change weights and looks great ifrom storage perspective.

Compact and solid appearing. Have only had a week or so, but no problem with plates coming loose as some have reported. Very good price . Almost as good as individual weight dumbbells at a fraction of the cost and space taken up. Ideal for an apartment.
