The prices are normal, everything is professional.
I supplement the review in 2024: 2 years after installation, the Aqua metering pump purchased from them and installed by them stopped working. I gave them for repairs and diagnostics, they said "everything is fine", paid for the diagnosis, took it away, put it on - it doesn't work. I gave it back for repair again, they've been buzzing for a month, they've stopped picking up the phone for the last week.
A mess and a disregard for a long-time client.
