Lectrosonics' LT series transmitters are arguably the most affordable way to get into high quality wideband RF for your lavalier microphones. However, it's not a perfect device. The body shape is a little big and a little square, the battery door can become unreliable and need a little maintenance (which is fortunately easy to do yourself), but the most trouble I've had with these transmitters is the stock wire belt clip. It's just a firm steel bent metal wire that provides almost no friction to whatever you clip it to. The good news is, it's easy to put on, it's easy to take off, and it's easy to remove entirely if you prefer to put the transmitter in a pocket or inside a strap. It's fine for stuff where talent isn't moving much, but when talent starts moving around, you're taking chances. I've had them fall off of talent on more than one occasion, which is embarrassing and can damage my lav mics. Lectrosonics does make an alternate heavy duty clip (part number BCSLEBN) that can be bolted on. However, it costs almost $50, makes the LT transmitter even harder to hide on talent, and is not easily removable.
