Its a monumental waste of money.
I have a device that I end up getting the heated trio or something like $800. I took 2 1/2 years for me to receive the device and then it ran for about a year and a half before it finally just stopped running the company told me that the warranty had expired and that if I wanted to get it fixed, it would cost $150 and I have to ship it to them at my own cost. Here’s the problem all that mining that it did was only $150 maximum worth anyways and it cost me two rounds of filters of $35 each so basically it’s a huge money. You never get any money back. It’s actually just better to buy bitcoin.
