I installed it today, 21/11/20. Very difficult installation if you consider that I connected it to a wall-mounted bathroom supply. The company Primo is Greek and the products are relatively good and affordable (value for money). Construction-wise, it could have had the ability to easily remove the cable in order to connect it more easily to the supply. (Meaning, it is intended for the bathroom and there is no base to support it on the floor, only a small bracket to hang it on the wall. Also, only a power cable is provided from the socket.) Otherwise, the construction is very mediocre. (Expected for 13 euros). I believe it will at least last for 3 years.

Within a few months, the resistance cylinders turned black and it no longer heats up, even though it consumes normally.

I have it for 3 years.
It is used only in the bathroom for extra heating and it is super efficient and instant.
Cheap and good, I highly recommend it.
OF COURSE, all these are for limited use as they consume a lot of electricity.

I would not buy it again. Very difficult installation, below average construction, and in a small bathroom it does not work well. Low price but for me personally, a bad purchase.

I bought it in 2016 to temporarily heat the bathroom (small). I don't have it permanently running since I use it as a supplementary heating method and based on that, it is quite efficient. All of these consume a lot of electricity, so I use it sparingly. It is well-built, waterproof, and for its price, it is okay since it hasn't presented any problems in 3 years.

Economical and effective device for those who want to quickly heat a small space (ideally a bathroom). I'm not sure about larger spaces. It has 3 settings. Usually, for quick results, I put it on the third setting. It has a short cord for the outlet and may need an extension.

For its price (at 13 euros), it is excellent. On the third level, in very cold weather, it heats up a small bathroom of 5-7 square meters in no time. Aluminum facade. I have had it for two years. Highly recommended!!

A classic Chinese hailstone stove. I have installed 2 similar ones before, but this particular one has the most difficult mounting system. The screws that need to be screwed in are right behind the stove, and it is not easy to position them with a short screwdriver.
