I purchased 22 of these guitars (some 3/4 size and some full size) with grant money for a children's guitar ensemble. For the moset part, the guitars are more than worth the cost. Out of the 22 guitars, about 6 buzzed on any pitch played mf or louder on strings 6,5, and 4 because of the string action (most of them were 3/4 size). Although the guitars come with an allen wrench, it does not appear that the action can be adjusted. Several of the guitars play very well and have a decent tone. It took several weeks for the strings to stabalize enough to stay close to in-tune. There are little problems here and there with the workmanship, but for an inexpensive student guitar it fits my needs.
