CoolAir personal cooler terrible quality and 10x overpriced

The personal air cooler CoolAir is advertised on various sites on internet. The impression is that it will be delivered in a few days, no shipping costs. Actually it is shipped from China, only to be discovered after ordering. Once paid per credit card, I discovered that about 10% was added to the advertised price. I ordered 5 units, they arrived one by one, 6 plus weeks after ordering, and I had to pay R26 or R37 per unit at the Post Office where I had to collect it. Why the difference between identical units, I could not figure out. On one unit, I was told to pay R627 extra at the Post Office, which I refused; I then had to write a letter, telling whoever decided on the extra costs (probably SA Customs), that they must have made a mistake. So that unit was sent back to Customs by the Post Office to fix their error. Now, 7 weeks after ordering I have 3 of the 5 units. I had to fix two of them; they were leaking water. I opened them, up to the point that will have to be done in future, if the units last that long, to change their water absorbing "filters". This changing of filters, was only discovered after reading the instructions, which also is not known before receiving the unit. These filters will probably have to be ordered from China, not recommended at all by me. When opening the units, it is apparent how terrible the quality is. The leaking is probably due to a crude valve system that does not work properly, therefore all the water in the filler tank on the side runs into the container at the bottom, causing it to overflow. The "solution" is apparently not to fill the tank on the side more than 50%, which is nowhere specified. Many of the plastic brackets inside the units are broken, so most things are lose and/or flimsy. The unit can still basically work with them broken, but it clearly shows that the unit is totally overpriced for such a low quality and cheap design. The mini USB port on the unit, looking at my 3 units, are badly aligned, or so lose that it is hard to plug the USB cable into it (it needs this to power the unit). I shall leave the cable attached, because it will surely break the wiring in future when reconnecting it a number of times. On the box, it is written that the unit is 350 W. In the instructions booklet it is specified to be 10 W. This is not due to input and output power being specified, the input power is roundabout 10 W. The 350 W is totally wrong. Is the unit working at all? Yes, a little bit as could be expected from such a product, but it is noways worth the trouble and costs. It should have been 10 times cheaper.
