These aren’t my favorite adjustable dumbbells, but they are solid nonetheless. Sometimes the cage is helpful, sometimes it’s in the way - for your own gym this is almost completely a preference thing. However, I will say power blocks have the biggest, most obstructive cage of any other caged adjustable db, because it completely encloses both sides of the db. Another downside is the durability. The plastic pieces that you slide in to select your weight brake easily if they take a weird fall. And if it brakes far enough over they no longer hold both sides of the weight which makes it shift A LOT when you to certain exercises. That being said, they are still pretty durable, they are priced competitively for a pair of adjustable dumbbells up to 90lbs, and it is relatively quick and easy to change weights.
