What do recent reviews say?

Only five written reviews were available, so the picture is thin. Two reviewers praised the work and a named technician. Two others reported a messy visit, unhelpful after-sales help, and a bill above the quote.

Based on limited recent reviews, so treat this as low-confidence.
