Works, Simple to Install, Short range.

This is a very simple device. It is exactly what I was looking for. I have just installed it and it is working well, but I had to position the receiver close to the garage. It was hit and miss when the receiver was more than 25 feet from the sending unit. Luckily our garage is attached to our house. I just installed it today so I don't know how long it will work for and what the battery life is like.

Very cheaply made

The range on this product is grossly exaggerated! I would only use this product if the garage was attached to my house. Mine is 60 feet away and it's hit or miss if this unit can register the open/close status. and in the winter time, I was constantly changing the battery on the door module because of the cold.

Skylink Garage Door Monitor

Great idea but not reliable. Alarm does not always shut off when door is closed.

  • from Calgary, AB

Not reliable

I had to move the receiver closer about 50 feet away. It still is not reliable at shutting off. I give 2 stars but I can't enter that on this review page either?

Skylink Garage Door Monitor & Alarm

The product was delivered in 3 days ordering and was a big surprise for me in internet purchasing. The setup was simple as exactly in the manual. The unit is working perfectly so far after more than two weeks. As for the beeping noise, I like it to be that loud so that I can hear it from anywhere in my house.

Easy to setup and use garage door monitor.

It's very easy to install on garage door. Also this monitor can control or setup for 4 units in future (garage doors, windows, or using basement). Very helpful to assist the home alarm system installed. Thanks to Best Buy for supplying this kind home device.
