Bowflex SelectTech 1090 Adjustable Dumbbell (Single)

I received these as a gift (they were bought off Amazon) and used them probably10 times before one of them broke. Its stock on 5lbs and the dials will NOT turn at all so you cannot remove the dumbell bar from the stand with any other weights. I contacted Bowflex and they wouldnt not even speak with me without the original receipt. (Im assuming based on other reviews they receive these types of calls often) . These dumbells are VERY: expensive and need to work for YEARS to offset the cost. Im very disappointed.
