Pro BreezeMini Heater - 500W Ceramic Fan Heater with Built-in Thermostat, Heat Dial, Overheat & Tip-Over Protection - Personal PTC Electric Fan heater Ideal for Over or Under Desk Heating

I've given this fantastic little heater 5 stars overall because I'm very pleased with its build quality, performance, looks, size, safety features, and energy efficiencyHOWEVER I would also like to add a bit of advice for all the reviewers complaining that the dial doesn't adjust the temperature - or that it "does nothing" - or that the fan keeps blowing after the heater has turned itself off after reaching desired temperature - etc, etc, etc . . .First thing to say is that the dial on the front controls the THERMOSTAT - not the heat setting!As one would expect in a tiny 500W unit the heat output is not variable and there is only one heat setting, but the Thermostat setting is indeed variableThis is how it works -1. The dial can be set to Maximum, or Minimum, or anywhere in between, depending on how warm you wish to keep your heated space, which may involve a little experimenting with the dial position to get the heat level just how you want it - I keep mine permanently on the same setting and only switch on / off at the socket, this saves wear and tear on the dial and I find it much easier than bending down to floor level2. When the heated space reaches the temperature level that the thermostat dial is set to, the ceramic element stops heating up and the fan continues to blow air through it until the element has cooled down to below the thermostat setting, then the ceramic element starts heating again3. The fan continuing to blow after the element switches off, is NOT a fault, this is a good thing, for two reasons - firstly, it enhances the energy efficiency of the heater because a ceramic element retains heat for a while after it has stopped actively heating up, so keeping the fan on means that "free" residual heat is pushed out and you get a bit more warmth for your money - and secondly, the fan continuously "cooling" the ceramic element helps to prolong its life4. I have referred to the "heated space" rather than the "room" because this is not a room heater, it is a personal space heater designed to heat a limited small area5. The angle of the heater facia is NOT a design flaw - warm air always rises upwards and this unit is specifically designed for use at low level to waft the heat diagonally upwards, which I personally find perfect for under-desk use6. As the heater is designed to be placed on the floor beneath where you are sitting, or perhaps on a workbench or countertop if you are standing, the heat may not reach your optimum level if placed on the desk when sitting unless you are taller than average - so please take these factors into account when purchasing and when deciding where best to position it to get the heat exactly where you need it7. The underside of the unit MUST be in direct contact with the floor or other surface it is sitting on - when placed on a deep pile carpet or other soft or uneven surface, the safety switch may not remain pressed in and that will prevent the unit from operating - if this is the case you can place something flat and rigid (and heat resistant) on the carpet, then stand the heater on that - so if yours won't work when switched on, please check this firstI do hope this helps, and if I think of any more useful points I shall update this review as and when . . .

This is a good personal heater useful to sit under a desk (which captures the heat) and warm you whilst working. It is perfect for this use, and calculating electric cost about 6 hours of use constant use on max settings (Oct 24) costs about 70p.It has one heat output setting (there is no variable output) and the dial on top is a thermostat, which means the heater will turn off after it reaches the set temperature and come back on once it drops below. This increases energy efficiency but if you have it on anything other than max means it will cut out occasionally until it feels the need to heat again.The anti tip function works well, the heater is not excessively noisy, and it looks nice and appears to be of good build quality as with most Pro Breeze products.Be warned: it is not a room heater and is not advertised as such, and having used it in my 5 x 5m (ish) lounge it did a very poor job of giving any lasting warmth. Definitely best under or on a desk to keep you warm whilst working on chilly days.

I wanted a small fan heater in the range 450W - 500W which was quiet, ideally silent. Both these heaters are rated at 500W and the NEXGADGET claims to be ‘quiet as a whisper - 40dB’.I found both these heaters too noisy to be used in close proximity, such as on a desktop, however the Pro Breeze was significantly quieter (approximately 7dB quieter) with just as ‘whoosh’, pink noise type of character. By contrast the character of the NEXGADGET, apart from being louder also exhibited a whine with discrete components at 170 Hz, 538 Hz, 1.075 kHz, 1.108 kHz and 1.144 kHz. Over time the character of the sound became really annoying.I checked the power consumption of both on mains (247.5V at the time), and from a 230V inverter (229.9V) checking with true RMS meters.On mains the Pro Breeze consumed 518W but the NEXGADGET consumed 576W, which is over 15% above specification. On the 230V inverter the Pro Breeze ran at 510W and the NEXGADGET at 580W.Because of the fan noise the only acceptable mode of use for me was the have the heaters on the floor about 0.5m from my feet. Here the orientation of the Pro Breeze fan was an advantage because the heat was directed upwards towards me. The heat from the NEXGADGET passed my ankles and I didn’t seem to get much benefit.I liked the straightforward 3-way toggle switch of the NEXGADGET with the option of fan only mode. The thermostat on the Pro Breeze worked but a temperature could not be set in advance. However once one learnt where to set it by trial and error, a setting could be repeated. Even so its use was limited as, in any standard size room, the heat output is, by design, so low.In the end I returned the NEXGADGET and kept the Pro Breeze. At some time in the future I may investigate replacing its fan with a quieter unit but narrow hex security screwdrivers would be necessary to gain access.
