The products are. Wry average and the customer service is pathetic . In case you are ok with calling and following up with the company after every 3 months for your amc service and then after numerous phone calls and a wait of 2 months they will send someone for the service then you should buy the product.
After paying for the whole year , you will only have to track them for quarterly service for which you have already paid.
If you are ready for this frustrating and mess then go for it
