Apart from the principle handicaps the shutter technique (glasses clunky and heavy, dark picture, slight sporadic fibrillation, expensive) I can only recommend the glasses. Tested with a Panasonic plasma TV and a Philips 8605 it works perfectly. These completely hum-free (which you can not always be said of other shades). Also the comfort is OK. Processing is also part of the ordinary. Clear Kaufemepfehlung, for one of the best shutter glasses on the market, which also still work with different TVs.
