range 433 vs 900mhz

In my honest opinion the compustar will be much better don't use the 556uw unless you plan on giving up a key, they make a keyless bypass for that vehicle which has proven very reliable when i have used them. The 900 will get much much better range then any viper product, ease of installation definately the compustar. I have the 5900 installed on our shop van and I get barely any range from it if I try to lock it walking away from the van it tells me i'm out of range. The 900 has exellent range as well as the remote issues have been dealt with, no more reset issues as long as you're buying a new system you have no worries. I've gotten around 5000 feet range flawlessley with the compustar and it does manual transmission vehicles without extra parts. But if anything get the pro series from compustar much better than both. Just my opinion. Best of luck to you

The key to range is pairing up the proper remote control with the right antenna. I've had alot of experience with the Compustar systems and I've had to mix and match remote controls with antennas for customers to get the best range. Some remotes work better with other antennas from a different package for some reason. The new PRO series remote controls generally get about 1.25 miles of range from my experience.Jeff
