Yes, its cheap. The Desingtech is an upgraded A2000. All of the other on the market can do the same thing pretty much. The DEI is NOT for manual trans. The Compustar is. Those 22 have a great warranty and I think will last alot longer. When I installed the one I did in Korea, it seemed cheap. Alot of companies make alarms. Alot of them will probably not last all that long. The desing tech is the same as the compustar. It may have a temperature sensor but who cares. I had that feature on a Aladdin A2000. I didn't use it. Compustar allows you to remove the key and keeps the car running, also has a turbo timer. How they sense that the car is in gear is not really sensing. When you get out it keeps the car running. Thus the car is in nuetral. So it would be bad on a convertible. IF you want a RS on your car do what I did or get a Compustar.
I just don't like that alarm, especially if design tech hasn't made any changes. I don't know how much it costs now, they were like $200. The company, PME who made it stiffed me on some money that owed me and left me with 1 &1/2 of one of those alarms. I sold it on ebay for $140 with an extra brain. Turns out the guy who bought it used to come to my shop. He's a good shade tree installer. Both units were broke,bad, TU. That wasn't good. He had to get a new one from PME.
PME tried to sell the design of the Aladdin A2000 to DEI years ago at the CES show. They even gave a free one to DEI. What a bunch of idiots! DEI took it apart and tested it and said that it violated FCC rules on frequency and range. They contacted the FCC and we had to stop selling them at the CES show, we could only take orders on "new versions". I know that A2000 had the best range for the longest time. Compustar is probably the best now. DEI's range sucks but I don't care because, I only wnat it to start my car from inside work. Not so I can run out of the mall and and get my butt beaten or shot over my car.
DesignTech bought that design not made it. So I think they must not have a good R&D department. DEI and Compustar do. They keep making new models. Plus I don't trust a company that can't get their stuff sold at real install shops. They sell at WalMart. If it isn't sold at a shop that waranties thier work and or products don't buy it. Enough said.
