Didn't realize how much I needed one of these until my LED stopped catching every speck of dust between duels. The plug seats firmly and gives the empty hilt that finished, powered-down look instead of a hollow tube. Fits my standard saber fine, though I'd double-check if you own a thin-neck model.

Fits my saber perfectly and the tip gives off that nice glowing rod effect when the LED's on. I like that it keeps the dust off the emitter between duels too. Solid little piece for the price.

The threading is clean and seats flush against the emitter, so it looks like a solid blade tip when displayed. It's been sitting in my hilt for two weeks now and the LED protection is a nice peace of mind, even if I mostly just like the finished look.
