Linear Multi-code 300MHz 1-Channel Key Ring Transmitter Review

Average Reviews:

(More customer reviews)Out of well over 1,300 Amazon reviews, I have only given just two one-star ratings. Unfortunately, in spite of the glowing reviews from others on this product, I have to give my third to this utterly lacking Multi-Code single-channel micro transmitter. I needed a portable garage opener for a building that has a system that predates anyone who lives in the building now. Given its miniature size, this looked like a fine selection as it provides the necessary match to the increasingly rare ten-switch operation. In fact, I was excited that I received two of the remotes for the price.

I enthusiastically changed the switch positions to match the ten switches in the main component of the garage opening system. However, to my chagrin, neither remote worked with the system, even after I replaced the batteries included for ones I purchased at an electronics store. Luckily, I still have an old remote that works, but it is on the verge of disrepair. I could understand if one of the two remotes was inoperable due to manufacturing error, but for both to be inoperable, it shows me that there are non-disclosed limits to the compatibility of this remote to systems. Be forewarned that you will run this risk as well if you blindly purchase this product based solely on its ten-switch capability.
