Good extraction for small bathroom
First up, my bathroom has never had an extractor fan and desperately needed one. I'd been running a dehumidifier after every shower. I wanted an extractor to run on a timer facility, so went about taking a permanent live feed from the pull cord to a new isolator in the airing cupboard. Switched live was taken from the light to the isolator. The screws on the Kair extractor fan cover to expose the wiring terminals were very small but with the right screwdriver a doddle to undo. Wiring was straightforward and much easier than core drilling the gable end in a tight space. What I really liked was the ability to leave the fan body wired up in the loft space but bringing the fan chassis stand assembly of it down to the landing. This gave me improved workspace and where I screwed the chassis onto a board. I also connected the 1m flexible insulated ducting and then reassembled the fan back into the chassis in the loft. The board was then screwed down into position but sitting on some rubber grommets I had from a previous job. I set the fan timer a couple of times. First setting ended up running for 20 minutes after lights out. 2nd attempt had it at 12 minutes. Bit of trial and error getting it to the time you want it to run for. Thankfully, just a quick job to adjust. Extraction from the 100mm fan is very good. The fan itself isn't noisy but the suction sound is. It'll easily hold a piece of paper to the ceiling at the inlet duct, so plenty powerful. With the bathroom door closed and from other bedrooms, I can barely hear it. It's doing exactly what I wished for and I haven't now needed the dehumidifier. This item in my opinion was a fantastic price and I'm happy with the quality and performance from it.

Works well, could do with better written instruction/diagrams
Unit works as expected, good amount of flow with the max speed (2 settings apparently, not tried the other). Wiring diagram useless tbh. Asked for clearer instruction and was invited to call an engineer instead. Quick google and found a YouTube video - easiest way to see how to connect. Fitting easy once wiring sorted. Operation is reasonably quiet (wall mounted to keep off the ceiling helps). Overall pleased with the product.

I'm A Kair MultiFan In Line Fan Fan.
After a bit of a trawl through the available options, I chose this Kair MultiFan In-Line Fan to replace the unbranded one that had failed after over 15 years of service. The Kair MultiFan I chose is the 125mm version with a timer. It was a cinch to fit and wire up with different power setting choices. The fan unit itself separates from the mounting bracket and duct connections to allow easy positioning and fixing. The fan unit then slots back in between the duct housings and is secured by simple retaining clips which are held in place by small screws provided. The instructions were pretty easy to understand after got my head around them. I opted to wire it up for full power which involved reattaching the existing cable to the Neutral, Live and Switched Live terminals. A little plastic screwdriver is provided to alter the timer setting. Out of the box the fan turned off after about four minutes, a simple turn of the control adjusts the timer duration which I have now set to about eight minutes. It does the job of keeping the bathroom from steaming up far better than the previous fan had ever done and the noise level is only slightly higher and by no means unpleasant. It comes with a two-year warranty and only time will tell how long it lasts but, so far I'm very pleased with my purchase. Thank you.

Good quality for the cost.
Good quality and robust. The fan was easy to install and powerful without being noisy. Offers good air exchange rates. Excellent for the price.

Works really well
This is a very good bit of kit for the money. It took a long time to work out the wiring as the instructions aren't great, but its fairly silent when tucked away in the loft and the ease of fitting with its clips and brackets is just great. I had assumed that it runs at a slow speed all the time like my other one, but it needs switching for that, but the key thing was a decent overrun, and up to 30mins is idea.

Quality product
Replaces a faulty one (not this make) went straight in working fine. One tint criticism its a teeny bit noisy.

Very neat, 2 speeds with a run-on timer. Buy a reel of bungee cord and suspend it to avoid vibrations through the joists. Buy acoustic ducting for the inlet and it runs practically silent. Use aluminium adhesive duct foil / tape for a good seal.

The fan is much louder than expected and the build quality feels extremely cheap. The plastic is thin and bends easily. The stickers were applied crooked and looked like they had just been printed on a home printer. I have bought a FanGoFast installed in my second bathroom and it is much quieter and made from far better materials — the only thing it doesn’t have is a timer. If not for the timer function on this one, I would have returned it immediately. I don’t expect it to last long. Not recommended.
