service was prompt,courteous. instructions fell short, form factor changed
I ordered two of the remote door openers. Both same stock number. One came with a small form factor 1.5 in W, 3 H, 0.5 D. I bought a second as I thought the form factor would be great for my wife. The second, same stock number was bulky 2.25W, 3.5 H, 0.75 D. Manufacturer had changed. The directions for setup failed to address the shunt to change from 9 to 12 digit transmit code. So a call for customer service was required. Friendly & Courteous, but a time killer. Otherwise they both work great.
