Rated 5 out of 5 by from excellent training tool evenly weighted (not weighed) seems like good construction. Have been using regularly, and have found them very nice. I haven't owned any other kettle bells, but will be using the next size up when I look to upgrade to the next weight.

Rated 5 out of 5 by from Quality build and design. Love the beauty of the Onnit kettlebell. The logo on the bell looks nice and the matte black paint job makes it stand out. These kettlebells don't chip or rust like my previous kettlebells. Thanks for a quality product.

Rated 5 out of 5 by from a long way to say Onnit Kettlebells are good to go I own a host of Onnit Kettlebells, a 35, a primal 35, a primal 18, a 44, a 53, and most recently a 70lb bell. I've owned ADER, Kettlebell USA and currently also Own a Kettlebell Kings 88 which i bought just recently because Onnit now doesn't make anything heavier than a 70. So - why do I like Onnit Kettlebell - this isn't just a formed piece of steel, balance, feel and quality all matter and Onnit has these things. Ader bells had an out of balance feel and Kettlebell USA is just too expensive. Kings and Onnit are comparable I like Onnit and I like Kings. If your serious about kettlebell work then Onnit and Kings ought to be the front runners in your decision to buy a bell. If your a tourist amazon will sell you a piece of metal if you want a fitness tool go with the pros.

Rated 5 out of 5 by from Excellent Value Super happy with my Onnit Kettlebells. Great construction - well balanced, even smoothness, and textured well for gripping as well as those more complex movements where you need your grip to slide just a bit. Would definitely recommend!

Rated 5 out of 5 by from QUALITY QUALITY QUALITY! I’ve been practicing with Kettlebells for 4 years now and I just purchased my first kettlebell from ONNIT. I just finished my first workout with my new (28kg) and I can’t say enough about this Kettlebell! I have 10 other kettlebells from other places and this is by far the best Hard Style kettlebell I own. The grip is amazing, the balance is dead on. If you’re on the fence about buying a bell from ONNIT, rest assured you are getting a top notch product that will last you years to come. I’m so impressed with the quality, I’m going to purchase more kettlebells from ONNIT and get rid of some of my older inferior bells I purchased from large chain sporting good stores over the years.
