Can not understand the 1 star rating

So as the previous speaker has already said the device has definitely not the 8500W. All thing is not surprised at the price micht.
I bought the generator on 01.07.2012 and since then continuously in use. Had a similar front of me is gone but after 3 years break.

What I have been connected so far:

Angle grinder, welding machine (380 V), drill 1200Watt, kettle 2200watt, Kühlschrank1800Watt, TV, stereo system, car radio + 2x 100 watt speakers, etc.
Draws without problems.
Welder has 4300Watt Operation Period: about 1h45min had to weld together for Tor welding carrier. The Gerator has gone through without any problems.
The old generator has been through the not even a minute.
My neighbor has NEN Honda Genrator with 7 KW and the welder who had his problems.
Noise is as with any power generator which is not now the leisete.
At the last party we used the kettle + fridge + Hifi easily 8 hours.
Fuel consumption is between 1,2-1,4l per hour.

For what I do with the Mache he is better than me.
