    • excellent
Style: B2401 Garage Door Opener
If you are looking for a modern garage opener, extremely quiet and with all the advantages of intelligent technology (control from mobile), the Chamberlain B2401 is a totally justified investment. I recommend it 100%. An excellent purchase that has improved my daily life!

    • Great price, very quiet, internet enabled
Style: B2401 Garage Door Opener
This is a fantastic GD opener at a great price. I bought it to replace a 20+ year old Liftmaster (made by Chamberlain) and used the old mounts, belt rail, shuttle, sensors and door attach hardware. It fit perfectly into the old mounts but uses a different type of belt (20 tooth) than my old opener. I also had to get a longer belt than the 234” belt that came with it ($50 on Amazon). Once that arrived, it all went together well. The setup was easy, just follow the directions, and it is a LOT quieter than my old opener. I like the fact that you can open and close it over the internet using the app. Now my wife wants one for her garage door - arraaagh! ... show more

    • Great Product for the Price
Style: B2401 Garage Door Opener
I had a technician install this product for me. He demonstrated for me and explained to me how to use each item. I'm very pleased with the product I purchased. My garage door opens and closes smoothly with no loud sounds. It functions better than the previous model I used by another company's brand.

    • 7 foot doors only. 8 foot can be used with an additional kit
Style: B2401 Garage Door Opener
This was a replacement, so I could reuse some of the hardware from the old unit. Installation was easy with the app step by step; you can even move the diagram around to see it from different angles. I made a few mistakes with the wiring, but I was able to figure it out. For example, it wasn't clear to me that you had to split the sensor wires and twist together the white/white and black/black. Setting up the door movement was easy. I got the height exactly where I wanted it. Since installing the unit is quiet and operates well. I docked one star, because it wasn't obvious this kit was for 7 foot doors only. I had to spend another $60 for the extension bar and longer belt for my 8 foot door. ... show more

    • Excellent Garage Door.
Style: B2401 Garage Door Opener
Seems to be a very good Garage Door and works well. Not bad to assemble, but you may need some assistance in actually getting it mounted into your ceiling. It is not heavy, but when you connect the far end to above the Garage door, it is very likely that if you are solo that you will damage it. This unit does support WIFI. What I like about it is not using it to open the door, but more so to see if the door opens when you are not there. You can also remote from anywhere with WIFI or cellular capability open the door from remote so they can put a package inside, or even if you want to open it to allow someone else that you trust to go inside. There are a tone of options with this one. While the unit is not Noisy or over loud, you can hear it operate! There was 1 critical Part that was missing, and a quick contact to support at Chamberlin they had one immediately shipped out to me with out any questions. ... show more
