Received the dumbbells a few weeks ago and so far they work great. Wish they were heavier but with Covid19 messing up manufacturing and transportation networks you can't be too picky. The best part is the foot print is quite small compared to the 11 dumbbells the MX55 replaces. Adjustment takes a little getting used to, but once you get used to it, its a breeze. Finally, almost feels like normal dumbbells but you shouldn't bang them together too hard since its not a metal to metal contact.

Great product. Far more functional and easier to use and adjust than power blocks. Highly recommended.
