Mixed...
I received the inverter about a month ago, I put it in my garage for fear it would catch fire. At the beginning, it gave off a very strong smell, probably the varnish (???), and above all it heated a lot. Little by little everything is getting better (smell and heat), I put a small charge on it during this time. I will be able to use it in the house (I hope). I was an electrician by trade, so I had reservations about using it.
Otherwise, it has some interesting features.
