There is no question that the Arden Shakespeare is one of the best scholarly editions you can get at an affordable price. Unfortunaltely, this has resulted in a work of extremely poor-quality publishing. The print is pixelated and rough, the text margins don't align, a few pages edges are folded inside, sometimes you get scaled-down pages with the printing indicators for where the paper has to be cut and (at least in one paragraph), a different font than in the remainder of the book is used.
I was horribly disappointed by these shortcomings, but as a text I need for university, this is not too bad because I have to clutter the pages with textmarker anyway. But if I bought this for my bookshelf, I would probably consider returning it.
The content is of course enormously helpful for understanding the contexts and implications of the play, and is a valuable companion for any class focussing either on the play itself or on Renaissance literature in general.
If you need a good and reliable edition with many annotations and textual remarks, buy this one ;)
