I have one of these. Great little unit but if you're going to spray larger areas like a fence that size, they have models with a bit more flow. But for the 50€ I paid, it was an absolute steal. But, add a couple more hundred and you get a unit that can cover much more surface faster, this does like 5 square meters in 15 minutes. The beefier machines can go much faster. But for smaller jobs, this thing is great - furniture, and smaller areas in general. You can do entire fences but you'll spend a fair bit of time vs a larger Wagner (or some other brand). Oh - and anyone thinking of buying this, for 9€ I bought the accessory 1.4 liter container you can get for Wagners. It fits this one. So going from 0.8 liter to 1.4 really helps if you're going to spray more paint, don't have to stop to top up nearly as much.
I buy one a few month ago and i use it just one time, i finish with a brush… Not enouth power, its too slow Better put more money and have something more powerfull
