I ordered the Simple Universal Opener. When I got the opener I had to first teach yet. This kind of thing I do do not always easy, but after a quarter of an hour I have been taught the two gate openers. Ten minutes ago, I once again read the product description and have found that the remote control for the VCR 1K - is not compatible 433 MHz. In my remotes it definitely works. The gate can be from about 10 - open 15 m. I am very pleased with the gate openers Heinrich Müller
