Bests & Worsts Reviews from Amazon

I've had these for about a year bought from Amazon. I also have the lighter 552 set. With the 552s, I've never had a problem with them. However the 1090 have a very important design difference. If you look at my first picture, you will see that the 552 plate has an actual metal tab that the handle locks into to secure the weight. The other two pictures show the molded tabs on the plates of the 1090s. You can see in my year of personal use, that the tabs on these two plates have worn down, and the handle will no longer pick them up. Meaning those plates are useless. I have bought one replacement plate (high cost) already, but now that I have examined the other tabs I see they are wearing down as well. So basically I spent over $600 on dumbbells that are completely unsafe. I did call Bowflex customer service and was told this is part of normal wear and tear. Do NOT, I repeat do NOT but these dumbbells, even if you are impressed with the 552s. Total was of money.
