After using a SXK Billet Box for two years it's nice to have a smaller version. They've improved the panels vs. SXK BB. Same material but these are much more polished and smooth. Wish there were better options for the fire button. It's a very plain little disc of plastic. The drip tip doesn't sit flush and when first removed, one of the two o-rings split and broke off. SXK has done this long enough they should get that right. The display screen cannot be turned off meaning you have blue light in your face every drag. I understand there was no room to put the screen inside but why not program the "Original SXK 30W chipset" to allow the screen to be turned off? Also, the screen is not flush with the body meaning it's a pocket lint magnet. Overall I'm happy to have a smaller BB but I think if an authentic company designed this product, SXK would of made a better clone.

I thought these were wider. Can only fit smaller single 18650 mods. I planned to use these for all my mods when traveling (bought several) but they are not wide enough for any two battery mods. My E-petite (single battery) will not fit either. The height is good and quality is fine.

I ordered 4 sets for the family. The tail lights have been fine. The headlights are crap. 3 of 4 broken. One did not light up right out of the box. One had several led's that did not work. The clip that holds the light to the mounting bracket is so weak and flimsy that two just fell off the bike while riding. The rubber covering the top-mounted on/off switch falls out and is easily lost. Now rain can get into the housing which will cause something to burn out soon I'm sure.

My kid has the JBL speaker that goes in this and likes to throw it in his hockey bag for tunes in the dressing room. This case fits right and is worth it as those speakers aren't that cheap.

Lots of Youtube vids on these being built to help with assembly as there are no instructions. The different resistors and their locations were not well marked and required some guessing. Don't put the LED's in straight, bend them 90 degrees so they stick out from the tree.
