Usage measurement

There are no cookies, nothing is stored on your device, no profile is created, and your IP address is never kept. Because nothing is read from or written to your device, this needs no consent. If you would still rather not be counted, you can stop it here. Details are in the Privacy Policy.

Good Brightness, but Unreliable Connection
The light offers good brightness, but the connection can occasionally be unreliable, which may cause problems during a performance. Since it uses three button-cell batteries, I’d prefer a rechargeable battery system for improved reliability and convenience. Overall, the brightness is good, but the occasional connection issues can be a concern when performing on stage.
Thank you for this honest review. When the light cuts out, there are usually two causes: button cells running low, or a knock. The light can switch off when the stick takes a shock, for example when it hits the floor, without the unit being damaged. Because the LED unit sits at the tip, a hard impact at high speed can break it, depending on the tricks you play. If yours keep cutting out with fresh batteries and no knocks, write to us and we'll look into it with you.

Great glow
The sticks aren't exactly cheap, but if you want to impress in the dark, you should definitely get them. The effect is simply great. And they're perfect for a show too.
