I play a fair chunk of competitive fps games.

Construction and build quality are outstanding. Price is very competitive. It's also cheaper. For the price and the effectiveness, it's hard to beat!

L-theanine, magnesium, and chamomile tea promotes a restful sleep. Both the chinese type (camellia sinensis var sinensis) and the indian type (camellias sinensis var assamid) have l-theanine in their leaf's.

Dizzy, dehydrated, exhausted and headachy all day after taking it the night before. There are studies where some age groups have insomnia when taking it.

Maybe my experience is unique. Hard to know. Be very, very careful.
