Review: Great value and quality - Bought these to build up some strength ,completely new to this and now in my 60s ,but I used to do heavy manual work years ago ,but the muscles have now gone ,I bought the heavier set ,hoping I’ll be able to use them later ( but after loading them up I doubt it lol). Quality is great ,good finish on cast iron weights and good chrome on bars ,with a hand grip in centre of each dumbbell bar ,feels good in the hand and solid. These look so small ,but when loaded up, feels compact and comfortable but boy do you feel the weight.Easy to spin off the nuts to change weights. Limited use so far,but nothing came loose or fell off, I consider this a good value for money set.

## Questions & Answers

**Q: How firmly do the disks and the extension bar stay in place? Some sets rattle and squeak no matter how tightly bolted together.**
A: I've found that when using the dumbells, the disks and extension bar stay in place for the duration of the session. But when I go to do the next session a few days later, I almost always have to re-tighten the disks. But then again, I've found that to be the case for most of the sets I've worked with

**Q: Can the weight plates be sold separately?**
A: This will separate into it's different parts and if you wanted to sell each part you could do.
it is a good quality system

**Q: What is the thickness of the bars**
A: The thickness of the bar is approx 3-4 mm thick heavy and sturdy enough to take the weights supplied it works well

**Q: how long is the bar in total when connected?**
A: Approx 1 metre

### ⭐⭐⭐⭐ An excellent set
*by P***E on 31 August 2024*

Very happy with this set. The quality is good and value reasonable. The grips are decent and after a few months of use, there's no sign of wear in any way. With a single weight on each side, the lock ring holds very well, and I just need to give it a quick check every few uses, just to be sure. With more than one weight each side, the lock ring needs tightening often, but it's not really a major issue to do that, so no big drama I don't think. Oh, I noted some reviews of similar products mentioned a smell - I'm happy to report that these don't smell, so I guess they are well suited to the (corner of) the living room... I'd definitely recommend this set!
