want dumbbell for home use , but not a separate pair for every 5-pound increment -lrb- would require more space , have to build a rack for they , out of place in multi-purpose room , etc. -rrb- . the PowerBlocks give I 5 to 45 lb . per dumbbell , change easily in seconds , have even weight distribution with padding around wrist , stay securely attach , and be easily store when not in use . no complaint .
