Terrific Price. Terrific Quality!

[This review was collected as part of a promotion.] I finish my routine with fifteen squats while holding the kettlebell chest-high with both hands. My goal is to strengthen my knees and I believe this is working well for the purpose.

Really happy with function

The handle is really sturdy, smooth and not bulky. It's easy and smooth to adjust weight. Comes ready to go out of the box. Does not at all feel bulking with a lot of weight which was what I was concerned about. Really great product I just wish there was an option to purchase one for 50+ lbs as well.

The only portable option for a healthcare traveler

I travel for work & there isn't always a gym on site. I also have to pack my car with everything I'll need for my next assignment. So, space is limited. This is really the only viable option to hit all major muscle groups while taking on very little space. Other option have you disassembling the unit to change weight. What's hassle! When I didn't get this as a gift I bought it for myself because it's far cheaper & more convenient than a gym membership. I also own the SelectTech Dumbbells but they're in a storage which is why I was interested in these. Progressive loads are a breeze with the turn of a knob. No brainer
