I purchased a number of these Minut units a couple of years ago, spending hundreds of pounds on hardware. Minut.com have now told me I need to give them hundreds of pounds each year to keep the units operational or they will stop working. They did not inform me at the time of purchase that they would try to force me onto a subscription. If they had I would not have purchased them in the fist place. I consider the company to be extremely unethical with little regard for their customers.
