I have to get rid of this ,not because I want to just because I need the money for a prescription.It works perfect,no lag what so ever (I thought there would be when I bought it).Works for 50 hours on 4 AA batteries and has about 10 so far on the set in it.It has a good enough range that I can display my games on the TV in the living room and play out there (about 20-25 feet). I need to get 30 bucks for it,if you are interested just send me a PM and I'll get right back to you.Thanks
