Transmitter ET-400/402

Finally got this to work with my old ET-400/402 system after losing the original, and the buttons feel just as responsive as the day I first used it. Pairing was straightforward with the receiver, though I had to grab my own wall charger since that’s not included. Solid replacement for the price.

The pairing process was genuinely painless — it synced with our school's ET-400 system in under a minute, and the buttons feel solid enough for daily classroom use. Just remember you'll need to grab your own charger and clip, since those aren't tossed in the box.

Swapped this in for a spare and it paired with our existing receiver without a hitch. The buttons have a solid click that's easy to feel even when I'm holding it mid-lecture, and battery life has held up through a full week of classes so far.
