As a plumber, I have installed these. The times I ordered these over the years, I have received defective units. The gears didn't work properly and most recently the lever didn't properly engage the switch to trigger the boiler.

Even though the product is questionable I would like to say that customer service is excellent.

Given how important it is to me to have these things actually work reliably, I only buy the actual Honeywell valves and not the knockoff brands in the same form factor. The valve body itself is rock solid - I've never had a problem with one. The motors I've had fail over the years; fortunately when that happens you can replace JUST the motor onto your existing valve body if the valve itself is still working fine (make sure it isn't seized or difficult to turn, or that could've been the problem in the first place!) The Honeywells are significantly more expensive than the knockoffs, but the construction is precise for replacement and they do seem to last longer.One of these days I'll remember to order a spare so I can swap it immediately when it fails instead of having to order one.

One of my two zones would open when the thermostat called for heat, but wouldn't initiate the boiler and circulator to turn on due to the metal arm not pressing on the micro switch in the head. These are known to wear out over time and it's been about 12 years since it was first put in service, so it's not a bad amount of time considering how often it gets used during the heating season.All I needed in my situation was the controller head and not the brass valve, so the swap was very easy and it fixed the problem immediately.

Considering the ease of replacement, and the quality of components, plus the money I didn't have to pay a plumber to do the work, it was a no-brainer to just replace the entire actuator myself, even if only the end switch failed.
