Words and Graph Programmable Bike Wheel Lights -Wireless Custom Message,Ultra Bright LED - Bicycle Wheel Spoke/Colorful Bicycle Tire Accessories- Waterproof

Install was easy, programming was actually pretty easy. the custom message that I wrote was about impossible for someone to read unless the are riding right next to you and only displays for like 3-4 seconds. the program gives you 4 slots to input your own messages so I input the same message in all 4 slots so it stays visible longer. the main complaint I have is that the light displays all kinds of random messages and shapes and graphics. i bought it so i could program my own message, i don't want to see all that other crap and i don't see any way to remove it.

If you have medium to big hands, this is almost impossible to tighten to hub. The software seems to have a virus that my McAfee virus protection deemed as troublesome to remove. Beware!!!

This product is very easy to program and works exactly as described. It is shipped from China so it takes a little longer to get here but worth the wait for the price.

Didnt last 30!days.. start rusting around the screwsDefective for out door use .

Bought this for my dad he loves it
