J&A Jason Aerobic Flash Reflex Lights, Agility and Reaction Training System to Improve Reflex, Focus, Exercise for Leisure, Fun for All Ages (Pack of 4, White)

Great idea but dysfunctional quartet. 1 of the 4 lights refused to link with the other 3 despite many attempts on linking as per the accompanying instructions.

Its time consuming to set up. It only has 2 modes. The lights arent bright. They dont feel sturdy (but so far they havent broke). You cant control with phone or remote. Etc, etc, etc.I was hoping for so much more, but i guess thats why it so much cheaper than the other brands.I own a gym/nartial arts academy and it just sits on the shelf because nobody wants to bother with it.Its not the sellers fault. Everything they said on their description was accurate, its my fault for buying the cheaper brand.

The lights are impossible to see outside and the sound is hard to hear unless your are right on top. Indoors they are great. I use them for basketball training, but cannot use them outdoors, which is where the majority of my training takes place. I wish there was a way to magnify the sound or the light outside. I dont recommend if using outdoors.

Good product. Love the cat meow. Every once in a while the product would stop responding. Other than that a fun tool for training and reaction

After watching the instructional video on the Amazon platform, I had very little problem in getting the units to synch and work together. Daughter has been using them since to assist with her eye hand coordination as part of her goalie training.
