Works great...Door locks....Shock switch....Great distance on the remote....

This product works really well. I put it in my civic which people like to steal, but with this alarm it will scare them away. You can change th sensibility on there to what you want. The product is great all around. I would recommend this product to everyone it is affordable and a great investment.

this unit is great easy to install great options for 40 bucks.
only down fall is it does not have built in relays for door lock wires and unlock wire so i had to wire up two relays but for 40 dollars what do you want works great also the shock sensor is not that great set the sensativity all the way up and you have to pound on the truck really hard to get it to go off

I would definetly recomend this alarm! Especially for 40 bucks!! I'm 16 and I have a rather expensive stereo and I bought this alarm. I wired it all up it a day and I'm as happy as can be with it!!

i like the product and i liked the service too... thanks to sonic

Easy to work with no problems i have one in my other car.

The price was pretty good but it was too complex for me to install myself and ended up costing more than I had hoped. Just recently the unlock function one one of the doors stopped working.

I would recommend this alarm. It works great. The only issue with this alarm is that it needs a better antena for longer ranges. Other than that it does its job.

This is a great alarm for a great price, installed it myself, soldered and heat shrunk the connections. 1994 ford explorer

Installed system and hooked it into my door lock and ignition systems in order to control them with minimal problems.

I bought Crimestopper SP-101 about 6 month ago. It is a good equipment for that value.

I installed this unit and it works well. It is a little touchy. It will go off even with a stiff wind. This does make me feel good, better a little touchy than not work when needed

Got this alarm two days ago, hooked it up worked until last night. Everything works but led status light horn and siren. Checked all wires. Unit used to click when set off not now valet switch wont even work. Ton of complaints (can't return product, Poor customer support). Sonic Electronix is great but now I have to purchase another alarm and i just got this one two days ago. Im pissed but after reading all of the B.S. you have to go through to return, I'm buying a new one. Have too much investments in my car to lose them while i sleep one night.

I install this unit my self, diagram was well labeled and the unit work grate. i rate durability 3 because the speaker housing brake, poor construction other than that the system still works.

its a good alarm says what it dose every things been working fine alot better than the factory fob

For the price this gives you a decent car alarm. I would recommend this alarm to anyone who need a car alarm while saving a few bucks
pros: Value, Durability, Features
cons: None

Highly recommend CS-SP101. Easy installation and user-friendly programming. Install on a Ford explorer with no relay. It has advance features and well produced brand with a low price tags on the net.
