Going to preface this with the fact that I've only used one other loadable dumbell and it was the gungnir. Plates load fine, knurling is ok. Handle/grip is way too narrow. I bought this for one purpose though, to throw a fat grip on there and mimick circus dumbell best I can. The handle is too narrow for a fat grip. It slides around which isn't safe. I fixed this by wrapping string around the handle then tape to thicken it up and now the day grip stays put. So all that said if you're looking at this for a specific purpose outside of normal dumbell use then have at it. If you're looking for a good dumbell this isn't it.
Also the collars spin for some reason. Not really necessary unless you're training grip.
