I like Powerblocks, but I understand the detractors. People complain about the cage and I guess if you have massive hands that could be an issue, but it's never been a challenge for me. I think people don't like the aesthetic, which I guess is fair. I've had mine for about 6 years and I've bought the expansion packs up to 90lbs. They are a little oversized when you get that heavy with them, but I would imagine most adjustable db's are that way. I know these have gone out of favor due to some recent additions to the market, but Powerblocks have been around for decades for a reason. They're tough, durable, and affordable. I don't drop mine. Sometimes, my second expansion pack with stick, but it's a minor inconvenience.
