There are some threads here that bad-mouth either Globalscale and/or the various Plugs, but I take these with a grain of salt. These are "development" products, and they have issues. As developers or hobbyists we just have to struggle through these. My calls to Globalscale have been handled reasonably well. Some others report email is next to useless. I could be wrong, but I have the impression that the "Globalscale" facility is just a small import shop with few employees. They probably don't have the people or resources to respond to requests out of the ordinary. They do seem to be dealing with the GuruPlug heat issues responsibly, or at least they're trying to make good with a reworked model.
I do not agree: of course there are customers who want to be creative and mod/wait until it works as promised. But there is a huge
amount of customers who thought that they would buy a product out of the box that is tested (look at the QA pages at Globalscale's website). They are NOT working on a solution: they just downscaled the specs. And these suggestions still do not work: there is still a heat problem.
