Rebound nets

[bluecephas]

I play only on weekends, but would like to do some practice on the weekdays, and I wanted to know if anyone has ever tried any of the Tennis Rebound Nets like the Gamma Portable Rebound Net

How do they compare to a real wall? Does it produce enough rebound or adequate ball bounce? Any feedback would be appreciated.

A wall... theres not a real court or a read net.. so your hitting nowhere... the rebound net must be a good idea... because its on the court.. you can practice cross court down the line or something... like if you dont hit the net then the ball goes foward or to the next... use like 3 balls or something... at least you ll get a punishment for not having pinpoint placement... im real good at placement now... I can hit my pro when I want to :) I havent tried it... so I dont know... loooks like a stand up trampoline type thing IMO.
