The item was about a week late arriving due to issues between Bluetti and their courier. However Denny at Bluetti did a great job of keeping me up to date and offering options to cancel / refund if I was unable to wait. I am glad I chose to wait because the EB150 appears to be a very well made piece of kit. It arrived well packaged and fully charged and the little instruction book was easy to understand. I have run a number of tests on the unit and everything seems to be just as advertised. I can't comment on the longer term reliability but from what I have seen so far this looks like a robust and well made item that should last a very long time. I can certainly recommend it.
