Great looking kit once fitted. Now to ne honest the light sabre is pretty fragile once fitted as you have to remove the supporting centre rod but once it's all done it looks the business. In the light kit you do get clear circular bricks for the sabre as you can change the colour on the touch of a button (nice feature) i chose to keep with the red as it works how I display the kit.

I love this kit, made the displaying of my set look way better! Takes patience and time to install but not as hard as I thought it would be. Quick delivery and decent price.

A lot of fine cables for install, not so easy for make the cables unvisuable. Black cable on a white musroom. I have one connection port less., 9 cables for connection to the usb hub. I fix it with parts of another set. Nice color and you can dim the lights with the button. Its nicer with small lights than full lights. Small set, but the lightset makes it nice and cosy.

So I love the end product but the process of adding these after it’s already built is a bit of a pain. I also wish the instructions at certain parts were a little better. Overall though I’m happy with the purchase and again I love the end product definitely makes the set look better
