The Final Verdict

As the LiftMaster 3900 and the LiftMaster 8500 are compatible with many doors that are similar, the decision may not come down to compatibility. One thing that is worth bearing in mind is that LiftMaster recommends a maximum opening of 10 cycles per hour for the LiftMaster 3900.

Regarding size and appearance, they are both tidy, compact machines that will save you space. The LiftMaster 3900 has the slight advantage of being a little smaller, but we didn’t feel that this was enough to affect the buyer’s decision.

When you add the cost of an Internet gateway to the LiftMaster 8500, the price of the two is quite similar. The LiftMaster 8500, however, has a 5-year warranty, which makes it better value for money.

Overall, we preferred the LiftMaster LiftMaster 8500. The motion sensor light may not seem important but it was a huge benefit. The locking system is a necessity. And, to be honest, we liked being able to control our garage door from our phones. They may only seem like little things, but when put together, they make the LiftMaster 8500 superior.
