I got one of these back in 2021, then had a minor issue with the UV coating a few months later and instantly was sent a new one, no questions asked. Lately I’ve noticed the battery isn’t charging to full any longer and chatted with their support and they have a policy that if you have a failure in 2 years, you get a new one free, if after that up to 10 years you get a new one for 50% off. That’s a company that seriously stands behind their product.
And they are made in the USA (if that matters to you, it does to me).
