I got my adjustable kettlebell today and am a bit disappointed if I'm honest in the finish of it. For a start there's a few chips to the powder coating around the edge where the two halves of the shell join. Not a massive deal as it gets used as it's get a bit banged up no doubt.
More annoying is there are a couple of sharp burrs to the underside of the handle on one side. If you've holding it in the middle they won't get in the way but will do it you hold it slightly off-centre, and I could see these cutting up your hand. I suspect I'll be able to sand them down but still, I shouldn't have to do that to a new product (certainly not one costing this much and from a reputable brand like Wolverson).
It's disappointing that these QC issues weren't checked by Wolverson. As it is, they're probably not enough to go to the hassle (and cost) of returning the bell.
I've got a Black Series 20kg bell from Wolverson too (the older style I think with the colour-coded inlay) and the quality of that seems much higher than this adjustable bell. Obviously you're limited by a single fixed weight with that though.
I got this at a decent price in the recent sale (still expensive as a one-off payment but hopefully the range of weight will make up for the outlay in time as I get strong enough to go up in size), so I don't feel quite as bad about the issues I've found, but if I'd paid the full RRP I definitely wouldn't be massively happy with the product.
