    • I like them
Size: 105 lb Set -Two Handles Color: Black, 105 LB, Pair
These work really well for what I need them for. Some of the weights have small tiny tiny chips in them, but it really doesn't bother me. Small enough there is no way to tell a difference purely cosmetic. If you do roll them on the carpet or ground, the lock will come a tad loose. But for the price these are pretty good. ... show more

    • Great product. Wish the changeability was better though.
Size: 105 lb Set -Two Handles Color: Black, 105 LB, Pair
These are great, however just two points to consider if you are buying. 1). They take a while to change weights, simply because these are spin lock based. So you will spend a lot of time changing weights when you need to. 2). The weight plates are somewhat larger than 1" and so are the handles. Which means, you will not be able to get more plates and limited to the 52.5lbs per handle. However, overall I really like them and they fit my purpose. I don't plan on lifting super heavy, just need to stay in shape and healthy. ... show more

    • Decent Cheap Dumbbells - Read Before Buying
Size: 105 lb Set -Two Handles Color: Black, 105 LB, Pair
These dumbbells might be what you're looking for if you're starting a home gym and don't have the space and money for static weight dumbbells or high-end adjustable dumbbells. However, there are some pros and cons that come along with the product so allow me to walk you through my experience. Pros: The knurling is good, nothing special, gets the job done. These work with and without chalk as well as with straps. If you're used to a regular barbell with knurling, it's pretty similar. They're super cheap. Let's be real, you're considering these because of the $1-$1.20 per pound price point. They save space vs. static weight dumbbells. They take up the space of give or take 2 dumbbells. When they're not loaded heavy, you have to find somewhere to store the extra weight plates, which can be a hassle, but it's manageable. The weights weight relatively true. I was surprised to see that these weights are fairly accurate, and the inaccuracies tend towards heavy. I liked this. CAP Barbell has good customer service. One of the dumbbells had an issue and I had it replaced in a few days. Definitely don't hold your tongue if something is wrong with these. Cons: Something was wrong with mine initially. One of the collars wouldn't stay on and I deduced it to be due to the bar itself. They sent a replacement promptly - see customer service pro above. The quality of the coating is sub-par. It will flake off a bit especially when you first get them, and some of the plates may need a 'de-burring' to get rid of sharp edges. Dumbbell Bench Press and similar movements will be difficult with these because the bars dig into your legs pretty bad. I recommend getting a pair of tennis balls and cutting a small X in each one, slotting them over the end you'll use as the bottom. However, when loaded to capacity, this may not work as well. They take a surprisingly long time to load and unload. This is a hassle, and is one of the biggest cons vs. static weight dumbbells. You may spend a couple minutes messing around with little 2.5 and 5 lb plates and the spin locks, which can take away from your workout. Overall: 3/5 These dumbbells serve me decently well, I love using them for dumbbell flies, lateral raises, romanian deadlifts, dumbbell rows, and several other movements. However, their drawbacks make the price point fair - not better. ... show more

    • Great weights.
Size: 105 lb Set -Two Handles Color: Black, 105 LB, Pair
Love the old school feel of these weights compared to normal adjustable dumbbells. Only downside is they’re not easy to adjust the weights quickly since you have to unscrew and swap plates.

    • Heavy!
Size: 105 lb Set -Two Handles Color: Black, 105 LB, Pair
The quality isn't super high but their heavy and stay in place mostly. The paint has been chipping since day 1 and is sharp so beware, the grips pretty rough is really rough but very grippy, and the weights will loosen throughout the workout. All problems but nothing catastrophic. I notice these weights feel way heavier then the weights at planet fitness with the bar weight in mind do their heavy lol overall worth the money :) ... show more
