This works exactly as you would expect. It is cheaper than most and mine has been working for a couple of months now without problem. It fitted onto a standard Honeywell valve just replacing the old actuator. Just changing the head means you do not have to interfere with the water pipes at all and makes it a relatively easy job. Just put the two actuators to the manual position before changing so the valve stem is in the correct position relative to the actuator when fitting. If you do have a problem with a valve actuator and it is on the heating you can leave it in the open position which means you get heating when your water is on but that is not a serious problem in the winter till you can get a new actuator. The timer controls will still control the boiler coming on and off.

I swapped out (yet another!) dead 'Honeybad' valve with no problems whatsoever. Functions well. Looks like it will last as well as, if not longer, than the original. It is physically and electrically compatible with the 'Honeybad' product (the cheap gear mechanism is what usually fails in those - terrible design IMO). Note: get a qualified electrician to do the job! Buy hey... tips: **** Note: Do this at your own risk - get a qualified Electrician to install, check etc. !!!! SAFETY: ALL POWER OFF FIRST!!! Swap out the old for new, matching colour coding of wires. Take a picture first, to show original wiring! If the connection point has poor access, or is just crammed with other wiring, consider adding a 'flying lead' box to ease changing over valves: - The lead on old, inoperative valve was cut near the valve, stripped, and rewired into a... - Honeyw*ll terminal box (2 x 6way terminal blocks - so enough for 2nd valve when it fails!) - The new valve was then wired into the terminal box, like-wire to like-wire. This leaves the original, more complex wiring box, untouched. This is especially advisable if you have several zone values in addition to a hotwater valve. On a previous failure, the original terminals were crammed on my system and it was very difficult to remove individual wires and then try and insert new ones, whilst keeping other wires in place! **** Reminder: Do this at your own risk - get a qualified Electrician to install, check etc. !!!! :) Other tips: I found no problems - but do DOUBLE-check the connections - including INSIDE the valve - especially the Earth!! Don't cover the valves - they get hot as it is. Use minimum force to manually operate the valves - that mechanism is the weakest part of the design (both old and new)! Enjoy!

Seems well built and just as solid as the original Honeywell one. Only draw back (which may not even be an issue?) is that the lever doesn`t appear to spring back as far as the previous one. Upon releasing the lever, after pushing against the spring to force to open, the lever appears to not travel as far back to `closed` as the original one. Nevertheless, the valve still appears to go fully closed so I`m assuming it`s not an issue. Easy enough to replace like for like, even for a less experienced DIYer. I was apprehensive about buying a "fake", but so far so good, time will tell if it lasts though.

Got the heating system up and running straight away , quality item and a good price and fast delivery

Does the job and easy to fit

This was the second of these units I tried. Out of the box neither of them worked. The actuator arm does not contact the microswitch when in the manual open position. Hence the first was returned. When the second unit had the same problem I bent the end of the actuator arm so that it hits the switch and it's now installed and working. Even although this is about the cheapest one of these on Amazon it feels just as well made as the genuine Honeywell one, which had failed anyway.

Replaced my Honeywell Valve which had died a death. If you are considering trying to do this its quite easy. Online videos are plentiful including a very good one from H’well. After switching the power off you undo a small screw on the base and pop the cover off. Next remove the two screws holding it to the main valve assembly. NOTE It doesnt pop off as easily as you see in the videos. A bit of gentle tugging and a bit of prising may be called for. Once off check the valve movement to make sure its not seized. It doesnt turn far each way not even a quarter turn. As long as its free your good to go. This replacement appears to be of identical quality, the wires all matched and the included instructions were very simple and clear. One part I appreciated was it showed you where to orientate the valve stem before you put the part on. Very useful when you consider the limited movement. I lined the valve stem up, popped it on, tightened the screws, replaced the cover and connected the wiring. Switched on the power and all was well. A really easy DIY job made even easier with the clear and helpful instructions.

Update at 14 months: now the switch mechanism has failed. On the last failure an engineer just replaced the failed component but now the only other component has failed. That then is a total component zone valve failure after 14 months. Very poor. Update at 11 months: The motor failed and needed replacing so poor quality. My boiler cover paid for the motor so no return but it supports the old saying that you get what you pay for! I bought this because the reviews were good and the reviews for the Honeywell valve were about the same. However, that's likely the case because most happy customers don't post reviews and negative ones can sometimes dominate. Although I cannot yet comment on how long this will last the quality seems fine and was easy to replace the old failed Honeywell version. On opening 2 of the actuator securing screws were loose inside the device. These simply insert slightly (finger screw in) into the obvious plate securing holes - ready then to secure the unit in place against the actual valve. There are plenty of YouTube videos on this replacement task if you are unsure of how to proceed.
