It's very unique and customizable. It's a must buy for any fans if lightsabers.

This is so great! Light side, dark side, you choose and the blade is amazing!

Kyberlight sabers are awesome!

I ordered The Unstable Knight bundle with the silver hilt and crackle blade plus a regular blade and received it in just a little over two weeks. The hilt feels great in the hand and the weight is just right with a blade inserted. The light is really bright and the sound is loud and clear. I don't mind that you are limited to just three sound fonts because they all sound great and it actually makes it easy and quick to just pick a sound and go have fun.

Changing the blade color is easy too and one thing that I really like is that you can lock the buttons so that you do not accidentally change anything while playing around with it or filming it. I had that happen with another brand of lightsaber that I ordered, plus it was much more difficult to quickly configure the controls on, so it got sent back. The Kyberlight has a permanent place in my collection and I am sure I will be adding some more bundles, parts, etc... plus maybe getting a few more sabers for the family.

Missing parts

I thankfully got the blades and the main body of the saber, but was missing the separate pieces of the knight combo, I had ordered a different emitter and pommel at the same time which I did get.

Great Saber, but slow shipping

The product itself is awesome. Easy to assemble, looks, and feels amazing. The saber has great weight and balance. It's good enough to use for martial arts sword training and sparring, too. There are a few bright/dim spots along the standard blade, which is to be expected. However, this can be mitigated somewhat by filling the blade with a roll of clear celophane. Search youtube for a video on how to do it.

The problem is that I ordered The Unstable Knight combo, which was supposed to include a Crackle Blade. What I received was only the Knight Pack, and no crackle blade. I'm told that they are having supply problems, and the blade will be shipped separately soon. So I am in wait-and-see mode as of now. I will be happy to make this a full 5-star review once I receive my Crackle Blade and confirm that it's just as awesome as it looks.
