I hated the older FRS model before the X-serious...the only thing the FRS was good for was for my nieces and nephew to play with them inside the house and as Intercom..other than those two uses?? NOTHING

A waste of $$$$$ cause I had two other buddies brought them with me so we could talk trash while riding.....that NEVER happen so now I'm talking trash about them
NO really the older model suck major ju ju...three of us would try talking at slow free way speed around here in NorCal at 65 or even unsafe speed of 45 and NADA

...must have looked pretty stupid to other riders seeing us give more hand signal to eachother while having the non-Chatterbox stuck to the side of our head
The new X1 and X2,, of which I have the X1 but haven't had the chance to use it because it isn't compatiable with the FRS headset or extention wire

which I have in abundance

SO I couldn't tell ya much but if you have riding buddies and want the best??? AUTOCOM is the way to go. Advertise at 205mph...NO really they . They work. ANyone that has one has told me nothing BUT the best about AutoCom.
