Summary
A useless trial
joymauiNovember 6, 2008
Pros
Nothing good here because there is no free trial. An activation window opens with the option to continue free trial with limited abilities. When I click that option the programs closes.
Cons
Can't say if its good. There is no trial.
Summary
Any "free trial" that does not include full program functions is a waste of time!

gueRe-UCBMay 31, 2006
Pros
Few options... everyone can use this without getting confused!
Cons
I read other reviews and actually thought this may speed up some my downloads... but I got the same connection as before... I think this program is for dial-up users only, or for people who have a very bad connection, cause I have cable and I don't see any difference.
Summary
Good but tough luck for LAN users.

I tested this on LAN and it didn't worked out very well, however it will increase speed for 56k, DSL and Cable Users. Easy Settings. You just have to restart.
Cons
Not Free, Doesn't really works well for a LAN connection.
Summary
Seems good

Pros
THis seems a very efficient internet speed tuner. I wouldn't give it 5, because I do not know how the registered version would function.
Cons
Not free

Pros
I use Rogers Cable Internet Service but my connection speed has always been slow. I read about this software in a PC Magazine and I decided to give it a try: It's simply amazing. I am now constanly downloading at 350KB/sec as opposed to my old 12KB/sec speed. Love you .NETSpeedBoost.
