Almost Gave It a 4-Star Until the Problem Was Resolved!

I was going to give it a 4-star out of 5, until I found out that the problem was user error on my end! After several uses, I noticed that I couldn't get back the setting to the full 25 lbs on the dial and only stopped at 22.5 with one weight on each side slipping off. I clicked the dial and rotated, pulled and tugged, but with no avail. I thought the unit was defective. That is of course until I finally realized that the individual weights were not all the same height. That meant that the weights could not fully clip unto the main base with the red clicker button facing upwards towards me since it didn't have the height range needed to reach the handle base. With the red clicker facing me, the open slot side of the weights was also facing me, so it can't clip on. When I finally rotated the dumbbell the opposite way with the red clicker in the bottom, the weights fell unto the base and clipped on without issues. I was back to having the full 25 on each setting once again. If you are having this issue, you might have been using it incorrectly just like me!That being settled, I give it a 5-star. It is very easy to use. Being that it's adjustable, anyone can use it in the family with their weight preferences without having to buy extra dumbbells. If space is an issue in your house, this would be a great alternative to buying more than 1 dumbbell with different weights. If you are the kind of person that likes to throw their dumbbells roughly on the concrete floor (like some people do with standard weights), then perhaps this might not be the choice for you. You'll break the dial and plastic components if you throw this on the concrete floor. For people who do take care of their workout equipment so they can last long, this is a great set of adjustable dumbbells to consider!

Quarantine Sanity Purchase

Was going to purpose the bow flex dumbbells but these were cheaper. Great purchase. Use them 6 days a week. No complaints at all. Website seemed sketchy but genuinely an excellent product. Would recommend to friends.

Great quality, great ease of use!

So far so good. I purchased these for my husband as an anniversary gift. He expressed how easy they are to use, and are super convenient for in-home work-outs. He works from home, and these allow him to maximize his time when working out since we also have 2 kids. This product was also competitively priced when I researched against other brands.The only reason I gave 4 stars instead if 5 is that the base of the product was cracked when we received the item. After emailing the company, they quickly replied they would replace no problem and gave an estimate of shipping time to be about 1 month. That is now coming up in about a week. Once we receive the replacement base, I will update review to 5 stars! Overall great product, and would definitely recommend this brand over others when purchasing adjustable weights.

Easy to use! Great product.

This is the perfect adjustable weight for a home gym. It’s well made, compact and easy to adjust. The weights are not in pounds… but it’s not a bad way to learn a new metric system.

  • Are these easy to use? Super easy
  • How would you rate the shipping time? Right on time

I purchased the lighter version (27.5 lb) of this brand but wish I had purchased these 55 lb per dumbell set. Easy to adjust, handles are way better and gives you lots of weight adjustments. It can be a little bulky for us shorter people but does the job nicely! Highly recommend you make the spend on this one that goes from 5 lbs to 55 lbs per dumbell. Wirth the money!


The Best Dumbbells Ever!!!!

I had always wanted the convenience and consolidate my Dumbbell weights for my home gym. I took a chance on these and they are exactly what was needed. These weights take a few workouts to get used to, but once I did, I was hooked Glad I took a chance on these!!!!


Price and quality

Couldn't wait to use them.
