Ring circuit, is the execution correct?

Good evening The hot water ring line is okay as it is. Cold water can be done like this but it doesn't have to be. The Ibox should definitely be fixed at all 4 designated spots; otherwise, it could bend at the other spot because these plastic fasteners aren’t as stable as they look (this happened to me). The insulation should definitely be on every part of the pipe; otherwise, heat will be lost there, possibly also condensation at that spot. Pipe laying can be done like this, but it doesn’t exactly speak well for the plumber. This is how it looks at my place:

Hello and thanks for the reply. Actually, it doesn’t really matter if the pipes are laid nicely, since the plaster goes over them anyway, but it still annoys me because it was just slapped onto the wall carelessly. It looks similar at your place too.
