Scytek ASTRA 4000RS-2W-1 Remote Start 2-way Car Alarm with 2 Remotes

It does everything it's supposed to do, but there are devices with more features for not much more money. This one has only one auxiliary channel which you'll probably use for your trunk. If you want to roll windows up and down by remote you'll need one with more channels. Check out the ones from Autopage.When I unpacked the unit I picked up the hood switch pin. I pressed it a couple times and it broke. The spring went flying somewhere and was lost. If it couldn't stand up to the stress of my hand it certainly would fail inside the engine compartment.*6 month update*The two way remote has stopped receiving confirmations, so it's not much of a two way remote anymore. The display is corrupted. The lower right portion is a black smear. The battery cover falls off easily. If I gently toss the keys on the couch or am less than careful unlocking a door it falls of off.I would recommend not buying this.
