not much to say really , its a dumbbell - great for the home if you have the space , and I would definitely recommend get a rack if you buy a bunch of they . as dumbbell go , these be some of my favorite . they be very well make , and will not chip or crack - very sturdy . and even if the paint come off the number , the number be raise so there will not ever be any confusion as to what weigh what . I personally like use the hex shape the best . why ? well , two reason . for one , when I raise hex dumbbell over my head to do press or flye , I seem to be able to balance they better , although I know there be probably no `` physics '' reason for this , probably all in my head . secondly , when I be do flye or overhead press with dumbbell that have large diameter plate , and they touch in the top position , the edge of the plate can hit each other funny and make you dumbbell tip awkwardly - which never happen with the hex dumbbell due to they round shape . but I be rambling . if you be look for single dumbbell , these be a good choice and might be the last one you 'll ever need ! also recommend  smokin ' hot gun !! : how a average Guy can get Big , muscular arm in one workout a week
