I purchased four of these in 2013 when I decided to buy myself a touring mic package along with two Se1A's for overheads, a sennheiser e901 for kick and a beyerdynamic mc930 for hi hats.
Using the E904s for Snare and three Toms gave me just what I wanted. They captured the tone of the rock Kit perfectly in every circumstance, I have since used them in all types of genres when I'm mixing and really couldn't fault them.
Thankfully working with good Drummers these mics have virtually have no sign of wear or tear and the clamps have been though hundreds of gigs since and have not let me down yet. Definitely a great mic.
