Well made but expensive. Take up a decent amount of room on the dumbbell handle so if you have bigger hands they will rub against the plates for some lifts.

I appreciate the intent of these and regularly use them to progress things like lateral raises. I've had some issues though. Of my set of 4 1.25 lb plates, only 2 reliability open and close as intended. For an item with a premium price point, the build quality is not what I'd expect.

Most people might look at these and think they're not necessary, but if you have a fixed set of DBs, you can basically double their use and halve the footprint by adding either the 1.25 or 2.5lbs plates. I have a set of 5-100dbs in multiples of 5 and the 1.25lbs plate set now gives me all the inbetweens (ex: 12.5lbs, 17.5lbs, etc).
