Garage Door Not Closing Light Flashing

I bought this for garage door openers.

but it is unsettling to have the upstream light flashing

I have 3. One in my garage one in my foyer(vaulted) one in our bedroom. Working outside with garage door open is fantastic.

Because I was using one of these I don't have to replace my Garage Door Opener because it got fried!I just have to replace the cube for less than $.

I bought this unit to allow me to move high capacity disk drives between machines for video editing. It does exactly what I wanted. Moving drives is just a matter of opening the door, sliding them in, and closing the door. Te computer recognizes the drives, and I'm back to editing, rendering, or capturing files. The only comment I have is other reviewers say the doors are hard to use. To me they feel right. Like closing a door on a high quality product with a snug fit. When you close it, you know the drive is ready for work.

Easy as opening a small door, moving 2 latches, pressing the DDR4 into the 2 slots, closing the latches, put small door back into place, start up iMac - what once was 8GB now 40GB at 1/4 what Apple would charge.

[This review was collected as part of a promotion.] I just used it to our garage door opener and the batteries seem to hold fine. I received these batteries as the sample, but I think I will purchase this brand as a great value.

[This review was collected as part of a promotion.] These batteries have been great for my garage door. I’ve had an issue where my garage pad kept draining all the batteries I’ve used until I put these in. So far it’s been a month and the garage still works well and I’ve had no issues with the battery life! Overall, I’m very pleased.

I am in the garage door business and when I install new garage door openers I add a surge protector so the circuit board is not damaged from lightning or a power surge. These Belkin one outlet Surge-cubes are just the right thing for my work. They are self mounting with the plug, they are small, and they don't cover the other outlet.

Great quality yet not too heavy. This worked perfectly to provide a ramp in and out of the door from garage to backyard. No more lifting the grill or dolly thru the doorway. Stands up for ease of not in use to keep handy. Recommend.
