I love this alarm system because it works great for it's value. I needed to protect my car but I didn't need remote start and wasn't trying to spend too much. This was recommended to me by a friend and all of the features work great with plenty of aux outputs from the alarm if you want to control other things. The 2 way paging is great and the rechargeable remote is also great because the battery lasts forever. My only issues are the sensitivity of the on board shock sensor isn't very sensitive, but I believe part of that is how I mounted the brain. The other thing is that the remote tends to scratch and the buttons seem to wear out after a while much like TV remotes do after a lot of use. Still a great alarm for the price.
