Here's my video review of both the Initiate and Dark Initiate LE v4 lightsabers:
https://www.youtube.com/watch?v=9em2mZCFKXIThese are fantastic. I got them for dueling, with heavy blades, and they're great for that. I kept them basic, no covertec wheel, the blade color is fixed, didn't get any extras since I was looking to keep the price low since they're just for dueling, and they're exactly what I wanted.
The soundboard is super cool, loud with nice movement and clash sounds, and the flash on clash and blade lock look (and sound) great. I like the adjustable brightness and volume. The heavy blades can really take a beating, they're still quite bright, and these hold up for what I want them to do.
Thanks, Ultrasabers!
