I purchase the stand after have the 552 dumbbell for a week . I be do p90x and find it difficult keep up with the video with the dumbbell on the floor -lrb- and also worry about lift they off the floor and hurt my back -rrb- . the stand make it much easier and quicker to change the weight value and get back into position . the stand be really at the perfect height for I -lrb- I be 5 ' 10 '' tall -rrb- . I be impressed with how solid and sturdy the thing be . it do not budge when you drop the dumbbell on it . I be the type of person who hate put thing together . I must say , in all honesty , it be very easy to put together . I read a few review before I order it and be dread the process . I feel like the instruction be clear and all the hole be properly drill . it take I about a hour to assemble it .
