Unable or unwilling to fix product which never work out of the box

Shocking service. R 20,000 Portable Power Station failed after little use. Replaced only after several month, with another unit which never worked from the beginning. It appears they are unable or unwilling to stand behind their product. Within 4 years of ownership I had to endure endless waits and ultimately have never had a working unit. Now they even want bucks to return the faulty unit. Disgusting. Do not waste your money on any Ecoflow products.
