TL;DR (Too, Long; Didn't Read) VersionBought for the office to be in compliance with safety and fire protocols.The good- The size of the fan provides adequate coverage to make your feet or upper body nice and toasty. In fact, the fan will work so well that your office will produce a micro-climate of heat that will make your colleagues envious or angry (depending on how they see it).- This model is a lot cheaper compared to other similar models online or at a local store.- It does automatically shut shut off when the machine is being tilted, carried, or overheated. This is the reason why this particular machine is within office compliance.- It has a built-in carry handle and lightweight design for easy relocation. Just plug directly into an outlet and get cozy.- The unit is, for the most part, very quiet.The bad- You cannot adjust the fan vertical. It is a stationary unit and has to be moved around.- It is not energy efficient as a unit.Overall, is it worth it? A must have if you're looking for a heat fan that is within fire and safety standards at your office.TS; WM (Too, short; Want, More) VersionThe winter and spring months bring holiday cheers and merry thoughts, but it also ushers in the blistering cold and rainy days. Sometimes you just need that warm breeze between your feet or upper body to make you feel at ease. You can turn on the heater or fireplace, but your options will probably be limited at work. This is especially true if you're required to have a heater that falls within the fire and safety standards of buildings.But what is the fire and safety standards for fan heaters? Well the two features are; (1) the heater must turned off if knocked over to prevent a fire hazard and (2) it must have an auto shut off feature if it overheats. So if you're wondering if this unit has these two features then look no more. This unit does in fact carry those two features and is compliant for most offices. The model will in fact turn off very either tipped over, carried around, or is at near overheating. The sensitivity of the shut off feature when tipped over is quite high and will turn off automatically if you carry it from one location to another.It does draw in a lot of electricity however, so we suggest getting a dedicated outlet port in case of electric discharges. The unit cannot be adjusted vertically and can only be positioned where you want your heat to be discharged, but overall the unit is worth the purchase for those cold and rainy days working in the office.You Questions, Our answersDoes any have a problem when you turn on the heat setting and feel cold air blowing out on one side?We did not notice this when we tested our two units. Try turning up the fan or adjusting the settings.Does this unit have automatic shut off if it's knocked over?Yes it does. Works quite well and it is very sensitive!Can I plug this unit into a multiple outlet electric strip? I was just wondering. Thank you.You can, but be careful. Sometimes the unit does pull a lot of energy in the strip that might overload it (it happened once for us). We suggest plugging in the unit to a dedicated outlet for extensive use or using the unit within certain intervals (10-15 minutes) to avoid the electric discharge.
