What can I say, some people have had terrible problems with Mesh PCs but you can say the same about any manufacturer. If you do a search for any manufacturers you will find problems.
The only thing I can say is what has been said before. If a company sells more PCs than another then they will have more people with a problem than another company that sells fewer. Consequently if you look at Mesh or Dells you might see many people having problems but if you look at a smaller scale company there will be fewer people having problems.
The percentage rate might be the same but it looks like the bigger manufacturers have more problems. For example, if company A sells 100 PCs and 5% have problems you could see 5 problems. But by the same token if you look at company B and it sells 100,000 PCs and also has 5% with a problem then you would see 5000 problems. See what I mean.
Some people like Mesh, some don't, some people like Dell, some don't, some like PC World, some don't.
My advice, have a good look about and see what all the companies are offering and then decide.
