I bought my system 3 Toshiba with All Best around 3 years back. All best craftmanship really dishonest. They did left out my water pipe wide open without installing insulation. Hence I have very bad condensation and cause my wood floor cracking due to piping issue. Even vouchers that they give to offset maintenance, its also bull**** only allow 1 voucher of 10 dollars for 1 service. So even they give me alot also pointless they can over charge me and offset the vouncher. Due to their lousy workmanship the whole set of piping need to change and cost me 1040 to change whole piping. Hence making me to change a new set of air con. Never buy from All Best. If you want to buy from all best you need to do alot of homework first dont get cheated. And also, Dont because cheap then take. And just for info, courts are giving 3 years warranty for piping. Why they dare to guarantee that? because their workmanship solid.
