Transmitter Solutions Firefly 310LID22K Key chain Linear Mini-T Comp.

I did a lot of research to understand what would work with my gate, which uses dip switches and within the 300-310 MHz range. This product worked as intended

I got this for my motorcycle. So easy now to open and close both my garage doors from the bike, when I'm coming or going. I mounted the unit on my brake fluid reserve (I've clipped the chain to the cable for extra protection from any unforeseen wind gust!) The transmitters work as well and my car-visor units. Nice!

This garage unit is small, relatively durable, and efficient. I use it to open both the outdoor and indoor garage gates in my condo complex. The plastic casing and button are fairly strong. If I had to point out any cons, it would be that the battery life is not great (3-6 months or so), but that might be due to a key or some other object keeping the button pressed while it is in my pocket. Also, beware that the metal clasp is not very strong and the unit may fall off. I just removed it and attached a stronger key ring directly to the remote unit. Overall, the unit is good and much more convenient than carrying around a large garage remote.

Works for some months, then it suddenly fails.I ordered another one after it first one failed after 9 months and then the second one just broke after 5 months.Details:I use the big button for the door I always park my car at. After few months, suddenly the big button opens and closes the other door. So, pressing the big and small does the same thing. It is exactly like the big button is shorted to the small one. However, it does not open the door it is supposed to anymore. If I set both codes to be the door I want, then of course it will open the door that my car is parked at. The worst thing is that the unit starts sending signal ALL BY ITSELF without me even touching it. So, I'm going to grab water at 3 AM and suddenly see the garage door is open! DANGEROUSNow, you may think that is a one in a million defect. You are wrong! I ordered a second unit, and now after 5 months, this happened again! I woke up in the morning and realized the garage door is left open. I didn't realize why until I used the remote. It is 100% showing the same behavior.The first time it happens, I contacted the seller but I didn't hear back. So expect the same quality for the customer support.

And when you receive it you must open it to remove the plastic protector on the battery. And then it is very difficult to separate the cover from the base. Minor pressure on the indent will scar and crack the plastic cover.

This has a timer that automatically cuts the signal off after about 5 seconds. No big deal for a momentary activation but the safety on my hydraulic hangar door makes you hold the button to close it so after every 5 seconds I have to re-push the button. I'm sure this was to save batteries during an inadvertent button push but I wish there was a way to disable that feature.

I needed a dual opener for our house and my wife's parents place. This works perfectly. I bought this particular one because it was so small I could place it in a recess on my drivers door near the bottom pocket. A little epoxy and now it's mounted there. Don't have to carry it around and it's always in the same place without having to be clipped on.

I must have purchased at least 10 or more of these over the past few years and I'm just now posting a review. Excellent replacement for the original bulky remotes and very sturdy and well put together. Don't let the size fool you, the range is easily 3x that of a brand new full-size Linear Remote. All of them are still on their original batteries and still going strong. Beware they are easy to misplace and I've lost more than a few already, but they're inexpensive and very much a better alternative than even the originals. Word spread around my gated community and now many have replaced their original remotes with these.
