Ban Leng attracts strong praise for friendly staff, fair prices, and fast delivery, but faces serious complaints about installation quality and appointment reliability. Multiple customers report faulty work (reverse wiring, water leaks, piping problems) and slow responses when repairs are needed. Some installations lack professional standards, and appointment no-shows appear to be a recurring issue despite the business operating 7 days a week.
