There will be many thousands of people who buy a Mesh computer and have no problems, me included. These thousands will not say a word on the net about how satisfied they are.
There will also be hundreds of people who buy a Mesh computer who have problems, and Mesh will make mistakes. These are the people who will scream from the tallest tree about how bad Mesh are as a company.
For what it's worth I think if you buy a Mesh and have no real problems, then you will get a good machine for little money. If you have problems then their support can be a little lacking.
There are other suppliers who have better support reputations.
You pays your money and takes your choice. Sorry if that doesn't help much.
