Item worked perfectly...If your dampers have stopped closing correctly or won't open you have a choice... this option is just to to replace the damper motor and your saving are about half the price of the full damper assembly... I changed just this motor with half of my dampers and it was successful - perfect operation. However, what I found was that some of the existing damper assemblies were "sticky" even after cleaning with water and lint free cloths... Looking back, I wish I had just bought all new damper assemblies...to avoid the possibility that I'll have sticking dampers again in the next few years...Excellent product and 5 minute replacement time..

I don’t often write reviews and a product needs to be well above or below my expectations for me to take time out of my day to write a review. I’ve been frustrated with my old Honeywell actuators, as they seem to have poor build quality and a high failure rate.This actuator feels like a huge improvement right out of the box. I am optimistic that it will outlast the Honeywell actuators they I have on my other zones. Build quality is great, install is 5-10 minutes max.NOTE: I didn’t like the set screw as much on this new actuator, so I swapped it with the set screw from the Honeywell actuator. Just unscrew one and screw in the other of you agree. Otherwise, this product appears to exceed the specs of the Honeywell in every way.

Purchased to replace a more expensive Honeywell damper actuator that failed because of plastic gears. This unit has metal gears and work great. Has been in use for some time with no issues.

this damper motor replaced the existing perfectly except the set screw is not extend out past the body of the housing like the original making it a PITA to adjust and tighten. I would give this product a 5 star rating had it had a longer set screw. Unfortunately the unit I received had been obviously returned as there was second tiny set screw was installed under the original which took me a while to figure out.

These are working as a great replacement for my original Honeywell damper motors that were getting quite weak - often unable to move the dampers and sticking them either open or closed.I did find that the replacements were slightly mismatcehd in size -- the center-to-center distance between the axle and the side pin is 1.3" whereas the old motors were 1.325" and the dampers themselves are 1.375" (possibly a Honeywell manufacturing defect since there appears to be misalignment). That 0.075" difference meant that sliding in the VDM10 was quite difficult and moreover once installed this meant it applied too much side load and hugely increased the friction on the dampers, so it didn't even work! :-( Anyway, a quick workaround was to remove the plastic bushing from the damper where the side pin goes. That leaves a big loose hole, and then the VDM10 works quite well. Unfortunately this leaves a lot of backlash making it a bit trickier to set up.

Replaced a Honeywell that was seizing up with this and works great so far

Did not last 1 year, now there is a dead spot and sits there and vibrates or buzzes really loud until it engages. Buy a better one

The damper actuator for one of the HVAC zones in my house quit working. According to the documentation on the Amazon site this actuator was a direct replacement and the price was good. So, I ordered one. Installation was a breeze and, so far, the actuator has worked as advertised. I am a happy customer as it saved me a bunch of money over calling a repairman.

Just like the other reviews, I got this to replace my old Honeywells that were failing and sure enough. They were very very easy to install and work great! I also kept the old set screw from the Honeywell as others suggested and I highly recommend it as well. It fits perfectly and works so much better than the provided one.
