What are opinions on Colet coffee machines?

Disappointing experience. After about 1 month the machine started to stop dispensing coffee reliably. It ground the coffee but did not produce coffee in the end once in a while. After another month, the levers to adjust the coffee powder volume and fineness did not work any longer and the machine only produced a very thin brownish water although it continued to use the old amount of coffee grains. The seller took it back wothout problems because he had the same problem with the whole lot he had sold. I'd recommend to stay away from this Chinese brand and invest in some true Italian or other European brand (Saeco, Gaggia, Jura). Maybe the price is higher, but it will be worth it.
