Powerblock vs Ironmaster I have both adjustable dumbbells at home, with my purchase of the Ironmaster being for lifts like overhead triceps extensions and dumbbell pullovers that were difficult with the bulkier Powerblock design. Because of the design of the locking mechanism with the Ironmaster, there are fewer overlapping threads at higher weights, making it less secure at 75 lbs. Despite my cranking as hard as humanly possible, the dumbbell came apart while I was mid-lift, resulting in me cutting up both my forearms pretty badly. The plates barely missed my toes when they fell. I ordered a second set of pins for the weight extension, thinking that with longer threads there would be a more secure fit. They were slightly imrpoved, though because of their length they were cumbersome to switch out, making it difficult or impossible to maintain specific rest intervals for quicker sets, and they cannot be used at lower weight ranges. Also, their locking mechanism was still not as snug or reassuring as the Powerblocks. The entire collection is now gathering dust in the corner of my room, 200 lbs of paperweights. Novel design, but unfortunately a dangerous Achilles heel at the high end of the weight spectrum. Longer threads on the locking mechanisms would help, or a simple magnetic clasp or pin. I have had the Powerblocks for quite some time, and although they are slightly bulkier and more awkward, the magnetic pins have consistently held up, even when in the heavier range. *Update* After 2 years, the problem with insecure fitting of the locking mechanism has only worsened. I now rarely use the dumbbells, favoring the Powerblock almost entirely. When I need something less bulky, I have bought individual dumbbells gradually over time. For those that require the entire weight spectrum, this would be more expensive than the IronMaster, but it is cheaper for me as I also use the Powerblock. And it is certainly cheaper than a hospital bill for a broken toe, or stitches for a forearm laceration. This continued frustration has endorsed my earlier concerns about this product. I would advise my fellow Amazoners to avoid the Ironmaster. Great concept in theory, flawed in execution. Posted on Amazon.com
