A surprisingly beautiful microphone, especially for the price. Have used on Piano, as a cluster mic for a string quartet, and as a general purpose overhead/room/boundary mic; I can only sing praise about its dynamic capacity and clarity of sound. The sound is transparent and uncoloured, even with the high-frequency curve in the frequency response at ~4kHz. The mini-XLR connector is a bit less robust than the Neutrik equivelents, but the cables are still rugged enough to withstand regualr use, and long enough to avoid needing an extension in most cirumstances. My only flaw is that there is no current way to mount these mics onto mic stands, however the 4 screw-lock holes in the back leave pleanty of mounting alternatives for permanant installation, and the rubber backing isolates very well from surface-conducted frequencies.
If you're considering a boundary microphone, the E303 or the E304 are heavily worth considering, depending on which polar pattern you need. The polar pattern is clearly marked on the back of the mic, with the approprate direction, however off-axis response is significantly better than suggested in the literature - possibly a negative if directional capture is desired.
