Customers have mixed opinions about the grip of the kettlebell. Some mention it's comfortable, has a nice overall feel, and stores well. However, others say that it doesn't feel loose or make a rattling noise like they hear. The handle has straight sides, making some grip angles weird, and the handle gets slippery. The corner in its shape is not as comfortable as a traditional rounded, and it is a bit awkward for certain kettlebell exercises.

"...Grips are fine as they are, just wish they were a little wider for 2 hands. It’s a bit of a tight fit for 2 larger hands...." Read more

"...The handle is my biggest gripe. It’s skinny and smooth, so it doesn’t provide the best grip.-..." Read more
