There are reviews for the similar model that has the timer function included, but to be honest, this fan is very efficient, so unless your bathroom gets VERY steamy, you wouldn't really need it. I had another smaller inefficient Manrose extractor fan fitted in the loft, when the bathroom was refitted 3 years ago. That one,Manrose Shower Light Extractor Fan Kit chrome or whitewas fitted by an electrician at the time, but it wasn't up to the job & was rather noisy for such a little fan. It wasn't very durable either, packing up after only two years. So decided to invest in this one. Its considerably more powerful, robust in construction & without the timer function, easier to wire up, just two wires in my case!.
First thing that struck me, when I removed it out the box, was just how big it is! Compared the original (which was basically a 4" fan/motor, with simple couling around it, and a small box-cum-mounting bracket, containing the timer electronics.) This one is still a 4" fan, but the extra couling around it, means that it is approximately 10" long, 7" high & 6" across!
I fitted the mounting bracket to a piece of loft boarding & screwed that to the roof joists, but I recommend that you put a piece of rubber matting or similar, between the mounting bracket and boarding, to help reduce vibrations through the roofing joists. My one is situated directly above shower itself (in the loft), so I did this to reduce noise. Took me all of an hour to fit it, its very straightforward and simple to do, but if you're not compentant with electrical wiring, best get someone in to do this, but it'll only take a few minutes to do.
One handy additional feature on this model, is that it is possible to wire it for two speeds, if perferred. I chose to wired it for the lower speed, as believe me, in a modest sized bathroom, it is more than suffient! First time I used it, absolutely no steam formed in the bathroom at all! But I would recommend that you have a window slightly ajar, to allow fresh air to vent the room. This allows the fan to do its job properly, but does create a slight draught doing so! I found the room to be slightly colder after stepping out of the shower, than before with the original fan. It'll be interesting to see what it'll like in the winter! Easy to gain access to the working parts to clean, there is two arched brackets that loop over the fan assembly part, simply unscrew two screws, flip the brackets over & lift the fan assembly out. The brilliant thing here is, there is no need to undo the ducting, as the ducting is attached to two coulings couplings, that sit either side of the fan. Simple, logical & practical design sense! I also found this one to be quieter in operation than the original fan.
All in all, I'm impressed with this one, it feels like it will last, but unable to comment on durability as of yet, I've only just fitted it today! Hopefully this one will last considerably longer than the wimpy fan that I had before!
UPDATE: 02/05/14: I have now had this fan fitted for just over a year, and have had absolutely no problems with it at all, does the job! I used to have a small problem with mould forming in my bathroom from time to time prior to fitting this fan, not had any mould form in the bathroom since! Very impressed with this!
UPDATE: 07/09/15: 2 & half years have passed now, Fan still functioning perfectly fine, still no mould forming in my bathroom!
UPDATE: 08/09/16: Still good folks, no problems at all, went to clean the fan assembly a couple of weeks ago, which I've not done since I installed it 3 & half years ago, hardly any dirt to speak of, just a quick wipe of the fan blades was all that was required!
UPDATE: 12/09/17: Now getting on for 4 1/2 years since I've fitted this fan.....still going strong folks...no problems at all...superb fan! (That almost sounded like I want it to break down, dunnit!!!!) :-)
UPDATE: 17/01/20: It's still going! :)
UPDATE: 28/07/22: Yep..it's still going. 9 years now, no problems at all. :)
UPDATE: 19/03/24: It's still going! And I've never cleaned it in all that time!
