2 Garage Door Remotes for Linear Delta 3 (DT DTA DTD DTC DNT00002A)

On the DIP switch panel, the printed "ON" means off, compared to the original remote control that has both "ON and "OFF" printed. Otherwise, this control is easy to use, small, with good signal strength (opens the door 30 ft away). Good for the price.

Worked fine easy to set up … the picture is a little deceiving I thought the size was bigger. It’s a mini remote. My bad for not looking at the dimensions

These work great! I’m glad someone said it their review to set the switches opposite of what they are on the original. Other than that they work great!

I had my old garage door opener stolen from my car so I had to get a new one. These are pretty small in comparison but I like that! They are easy to hold, point and click but also easy to hide/blend in in the car so that they are not such easy targets for theft. I easily programmed them and they worked without any issue. They are responsive. If I needed more, I would buy these again. Just know that they are smaller than 'normal' garage door openers!

This garage remote is the standard Linear Delta kind with 8 dip switches. To work, besides the unit having a battery, the remote's switches each must be set to an up or down, for a total of 2^8 = 256 possible mathematical combinations. This is adequate for most neighborhoods.This would have been a five-star review, but I took off one star for the two glaring omissions.#1: The settings do NOT match what my working remote has. I figured it out: They are all reversed!Equivalently, one might argue that the numbers 1 to 8 were painted on the wrong way, reversing it all.#2: There is absolutely nothing about the kind of battery, how to open unit up to change, etc.Now, I grant that even a person of average intelligence will guess the second one. I took a knife and split the whole unit to get at the battery. (Actually, I did not go all the way - just enough to confirm location.)As for the first issue, the reversal, I realized that there is a certain arbitrariness to what is up vs. down. I could joke that China, which makes these, is on the other side of Earth, so up is down (in a dumb, joking way). Or maybe I saw this problem many, many years ago and remembered this.P.S. This practice of these tiny one-page "manuals" written in a tiny font has to be eradicated. Even products in the US, such as my $900 Google Pixel 6 Pro, come with almost nothing of a real manual. Anybody besides me remember the days of the giant 200-page manuals with big products (1980s)?UPDATE 19 June 2022 (within a week of original review)I edited a little, but primarily to change from three stars to four, because the thing does work and is inexpensive, so it really is good, not just fair.(Dr. Mike Ecker is a PhD mathematician, retired PSU math professor, computerist, professional reviewer, and writer.)

El único detalle es que hay que acercarse mucho para que trabaje

These are much smaller than the standard remotes but work just as well and not as bulky. Only issue so far is they seem a little delicate when pulling the halves apart to set dip switches. Haven’t used long enough to know how buttons and battery will hold up.
