Bought at Home Depot for $199. It is a toy, not suitable for serious work. Flimsy contruction, difficult or impossible to adjust. Recommend getting a brand name.

not bad but be warned you need to buy extra play-doh at local store before handing it to the kid's
Positive

THIS REFERENCE BOOK IS ONE OF THE BEST I HAVE EVER USED IN MY DAILY WORK AS A MEDICAL TRANSCRIPTIONIST. I FIND IT VERY USEFUL EACH DAY.
