Fantastic Adjustable Dumbbells
Excellent design! I bought these to replace my Eisenlink square shape adjustable dumbbells. These have a similar design, but the octagon shape is so much easier to use than the square shape that other brands have for the weight plates.This pair of dumbbells is built super solid and is one of the few adjustable dumbbells on the market than can actually survive an accidental drop (most competing products can break very easily).The weights are adjusted with pairs of 5 lbs weight plates and one pair of 2.5 weight plates that can be attached to the very end. The knurling on the handlebar is well made and easy to grip. The handlebar is thicker than static dumbbells, but still very reasonable to use. Overall these weight plates are highly functional, and I look forward to using them long term!

Great dumbbells!
I love these dumbbells. They’re the most solid thing you can think of, and the fact that I can extend them up to 160 lbs has me hyped about getting stronger. Also, changing the plates is easier than I thought. The screw moves in and out fast, and you don’t need to unscrew all the way out to add plates, just a bit more than the width of the plates.

Nice sturdy adjustable dumbbell
Just received these adjustable dumbbells today (one shown in picture). They are pretty well built, and the screw knob design is pretty clever. However, they also have some issues. Here are some pros and cons I found so far:Pros:- The material is metal, so they can probably take some abuse and last pretty long.- The screw connector are well designed and holds the weight plates on really sturdy so they probably won’t fall out easily. There’s also no slack between the weight plates once screwed in, which is not the case for many adjustable dumbbells with the twist handle design.- I didn’t notice any weird smell from the packaging, but even if there is you can just sanitize it/wipe it down anyway since they’re made of metal.- The weight goes up to 80lbs in 5lbs increment from 10lbs start weight, and at this price point it’s a decent deal.Cons:- These dumbbells aren’t as ergonomic as the ones at commercial gyms. The knerling seems to be okay, but the weight plates are bulky (probably a design choice to shorten the width, but could’ve chose a more dense metal for the weight plates) and the handles are a little bit too long (probably to support the screw pin design, this might be solved by a better design).- The weight changing process can be a bit time consuming, especially from very heavy weight to a lower weight, even though you don’t have to completely unscrew. So it can be pretty annoying to do drop sets on these.- The metal spoke that comes out of the weight plates seems to be glued in, so there might be a risk of them falling out eventually, but this haven’t happened yet.- This might be a bit of a nitpick but the metal screw do make some metal rubbing noise when screwing/unscrewing. But this can probably be fixed with some wd40.Overall, at this price, these dumbbells are really good for a home gym set up if you can put up with these cons. You’re literally saving both money and space. Only time can tell how these are going to hold up, but so far they seems pretty sturdy so I’m confident that they should last quite a while. I’ll keep updating this if anything happens.
