Question: Does the unit come with the belt?
Document: easy to assemble;did it by myself without helpyou don't need to pay someone an installation fee if you watch a couple ofyoutube videos on installing these things. its really quite easy and I'mnot very proficient with DIY projectss.
This one uses a 3V2032 lithium 5-year battery, commonly found, and inexpensive to replace. The code changing technology assures better security it is claimed, I will trust them on that. This is really an opener to consider seriously. I watched the installer work on this for 4+ hours. Unless you have the skills, time, and patience I would recommend you have it professionally installed. Doing that may insure a better warranty as well.
This garage door opener has been a problem since it was installed. We have had the installer here many times trying to fix it and he has given up. It is super sensitive to sunlight- I live in AZ and we get 350 days of sunlight on the average, need I say more?
They have discontinued the 3280 so he is actually selling the 8355. There is nothing wrong with the 8355 but I really wanted the 3280. Very disappointed.
I just had one of these installed as part of an insulated door & opener replacement. My old system was 18 years old. I am extremely happy with it so far and would highly recommend it. The main thing is in how very QUIET it runs. They have re-designed the inside of these and now they have near zero noise & vibration. In fact I cannot hear the motor running even while standing in the garage, only the sound of the door going up or down. Amazing.
Depending upon the angle of the sun, it is likely that I will have to go into the garage and push the door mounted wall button, keeping it depressed until after the door passes the sensors. Then I have to go around and let myself out the front door. We have tried creating shields against the sun, but nothing has worked. This is absurd! I have had many garage door openers over the years, even another one at this same house, but have never had a similar problem.
And the support from the company is non-existent.
Answer: no
