I use this from time to time when my left ankle gets cranky. Serves its purpose at a cheap price. Nice that they include a collar

These are far too light to get any actual strength results, but I do like these for warming up before grip sessions or just fiddling around while on a conference call. They've held up surprisingly well for a cheap set

Knurling is pretty passive, and there tends to be quite a bit of variation in the difficulty (not every #2 behaves the same). They're definitely a step up from amazon cheapos, but in this price range I'd get standard grippers from cannon powerworks 10 times out of 10

Growing up in Pennsylvania, a lot of commercial gyms had these dumbbells. I trained with these for about 2 years at the Hershey company (basement) gym in the early 2010s. The thin handles with no knurling make these far from my favorite dumbbell to use as a dumbbell. I've come to call these conjoined blobs.

While these certainly didn't have the cool factor of the original roundhead dumbbells, the current "gen 2" legacies are a solid option for an all metal dumbbell. Gen1 legacies (pictured) had some fairly major quality control issues, especially on the larger sizes where hollow voids were pretty common. That said, York introduced some nice quality of life features on the legacy dumbbells like thicker, knurled handles and size offerings above 100 lbs.

Really solidly built grip implement. I wouldn't recommend this (or most grip implements for that matter) for general grip strength, but this is a fun piece of kit for a contest. Bought this recently for an upcoming contest, but I've used this before at a friend's place

I've used this handle a number of times, and you simply won't find a higher quality grip implement. The 2.25" crusher with bearings, in particular, is the gold standard of rolling handles. It spins very freely, takes chalk nicely, and it's built like a tank. Very heavy duty. It's a little on the pricey side, and the ordering process is a bit weird, otherwise 5 stars.

Recently added this to my gym, and it's already one of my favorite grip toys. Luke from Arm Assassin made me a custom extra long version of the 2" variation. This is a great DOH axle accessory as it moves the weight farther from your wrist, making it significantly harder to hold on to even at lighter weights. Really nice option for wrist curls as well.
