No customer support
I purchased a Nanofoamer Pro from Subminimal which broke after a few months of use, just displaying a "\" symbol on any attempted use. I reached out to Subminimal customer support through the only channel available (email) and have effectively been ghosted with no response for over a month despite multiple emails being sent. Their customer support is non-existent and judging from the other issues users have experienced here their products seem cheaply designed and prone to breaking. Don't bother with this brand, given how much they charge it's just a waste of your hard-earned money.
