  • Looking for weight lifting equipment. Look no further!
Style: D.45LB(22.5LB Pair)
I am in love with this. Grip, look, well built though and built, easy installation, feel like a genuine weight lifting equipment, and value of money is excellent. Easy to adjust after each workout. Who ever designed this and made this, really put his or her brains behind this product.

  • Great set for home use
Style: D.45LB(22.5LB Pair)
These are really great for home use. Everything screws on right and nothing wiggles so you can be sure it’s secure. The padding on the barbell is cushioned which is super nice. The only reason I put 4 stars instead of 5 is because after so long you’re stagnant with weight. I wish you sold weights separately so that you could gradually increase weight or just select a specific weight that you want. If you want to lift heavier you have to just buy a whole new set with another barbell and hand weights. ... show more

  • Good quality, great for travel
Style: D.45LB(22.5LB Pair)
So excited to start using them. I love that it's easy to create combinations of weights depending on your workouts. These are great for traveling during extended periods (at in-law's for two weeks) but also for home. I'm working on increasingly building up my strength and I have 20 to 25 lbs. dumbells for the 5 lb gap is now fulfilled by these that are 22.5 each, plus they can be put together as a barbell. Very exciting! ... show more

  • They're OK
Style: E.70LB(35LB Pair)
I like these, and for the price they're pretty good but if I had known it'd be so difficult to adjust them, I would've gotten a different kind of dumbbells.
