acson product is very good. your team very helpful during purchasing process, guide me to solve some errors. Only one thing, the installation needs to be improved a lot. We need to build up customer trust. We declare our technician is certified installer, but the quality must be priority first. you can refer the attached photo as a reference. hopefully your team can solve this issue as soon as possible. thank you so much.
