Alarm works great, did not come with siren. Bad thing is batteries on controllers were dead and they are very hard to find in stores. Had to order some on Amazon. Other than that it great.

Outstanding for the price. I'm an electrician and my vehicle is simple, so I had no problem installing this myself. There's no real instructions included, just a schematic. You have to know what size wire to use if you want to extend the wires they supply and where to intercept the wiring in your vehicle, for example. Then you also have to be able to get to the wires, which are often under the dashboard and in wiring harnesses.

There is no sounder supplied with this kit. You have to buy a siren separately.

The alarm is a brain that has many features. I appreciate that you can use as many or as few features as you want. I installed the brain, the shock sensor, the blinky blue LED and a separately purchased siren on the first afternoon and stopped there because.... well... I just haven't gotten around to doing anything more. I put it on a classic vehicle. Around this neighborhood there's more brazen stupidity than careful thievery acumen, so the blinky light and noise maker scares people off. I had to extend the wires to put the LED, which flashes when the alarm is armed, up by the rearview mirror which makes it look like a high class installation. The fact that the LED is blue is great. It's better than the older red ones because the blue is piercing and scums can see it from the end of the block.

The features I haven't yet deployed are switches that would set off the alarm if someone opens the hood or trunk and a thing to open or close your electric locks. My vehicle doesn't have electric locks, but you can buy aftermarket actuators that will turn your old fashioned locks into modern remotely operated ones. I really want that feature but the classic is in storage at the moment, so I'll get there eventually.

The shock sensor has two different adjustments because it has two thresholds. You can adjust the force required for it make just a warning chirp and the force required for it to set off the loud siren. It is difficult to get this where you want it like at least one other reviewer said because the method it uses to detect shock gets set off by fireworks (which you have a lot of in trashy neighborhoods where an alarm is necessary) and by loud pipes on motorcycles, etc. The shock sensor is good in my case because even though I didn't bother to install the door switches yet, the shock sensor will set off the alarm from the force of someone getting in and slamming the heavy classic vehicle door shut behind them.

One small negative is that it's easy to accidentally press the buttons on the remote. I have occasionally hit the buttons as I'm getting the keys out of my pocket. Doesn't happen with the other alarm fob on the same keychain.

I bought this for the features and not really for the alarm. I wanted remote door locks on an older car that had power locks without a remote (88 Pontiac Fiero). Installation was a bit challenging but more due to my inexperience with the wiring in the car than the fault of the DX382, I had to purchase some additional relays to adapt the alarm to the power locks in my car but they were fairly inexpensive. Once I figured out where to mount it and how to splice it into the wiring, the alarm worked great, remote door lock features were more than what I expected, and I even wired the trunk latch to work with the remote. There are some programmable features like having the doors lock 15 seconds after you start the car and unlock when you turn it off.
My only real gripe is that the remote fobs use some weird batteries that are kind of pricey and I've had to replace them a couple times but not a big deal. You can't beat this alarm for the price, period! If I needed to add remote to another car, I would purchase this alarm again.

For the price, this is a great alarm. I installed it on my 79 k10 Chevy truck, so yeah this thing is most definitely universal! It comes with everything except an siren,( I just hooked mine up to my horn and works great.)
It's clickers are nice. It has an adjustable screw on the sensor, which it fantastic. That way you can adjust how sensitive the alarm trigger will be.
This product is such a good value that I'm gonna purchase another, just incase down the road I need another, I'll have it.
Do yourself a favor and get some butt-splice connectors and some crimps for it. Unless you prefer to solder the wires.

Key fobs look and feel nice for the price. All features work properly. The instructions were just bad though. Took me quite a while to get it all the way I wanted it. Tip I learned: when changing any switches in the brain, pull the neg terminal to the whole car. Anything less can result in the unit ignoring the new command somehow. The install had so many little glitches that proper documentation could have saved me.. that it took me 3 days of hair pulling to get it all right. Now that it's setup its quite nice. Another tip: solder all connections on something this finicky... otherwise you will likely have glitchy stuff happen. Range also seems to be extremely good. 500 feet or so and I live near some monster power lines, so I think that's pretty good.
Features I wish I would have paid extra for: a unit that the features can be programmed from the remote. I made the brain very hard to get to and having to go in there over and over to get it finally right was a bear. I feel that the quality of an alarm is 80% the install.. and most of the time install shops do a hideous job on them... so do it yourself for cheap.. take your time.. and have a great alarm.

PS. The shock sensor is super bad.. either way too sensitive or not enough.. the adjustment is more like an on off switch for most annoying sensor. I hate shock sensors anyway so I disabled it.
