alvotech is big scam, once you get their hosting they will lock your account after some time and ask for more money otherwise will delete your account and even not provide you the backup
of your sites. This could be nightmare for you.
I am not aware about that hosting service.Because i hosted my own site using TuckTail.com They have good server speed.I like their services.
If you want to know about their hosting service try to read hosting reviews
