Purchased a liftmaster telephone entry system (expensive). Worked initially, but developed problems. Spoke with liftmaster tech, ran requisite tests, received a warranty return authorization and eventually returned to gatecrafters under warranty for a repair/replacement. That was over a year ago. Nothing came back. Calls and emails went unanswered. The few times I got through to anyone at the firm, I would be referred to my "sales agent" who had multiple excuses ("factory down between model runs...", or "... we'll take care of it." Eventually nothing. If I knew they were just going to keep my expensive device, then I would have taken it to a local repair shop. Now, I'm out the entire value. Their promos are glitzy, but you can do much better elsewhere. Avoid.
