Bought 2 a/c’s and got koryo stabilizers as part of the package (ezone Chennai) one went bust in the first week. fortunately ezone replaced with a different brand. Bought 3 koryo geysers, 1 has not worked since installation. Koryo service has visited 3 times. now ezone wants me to followup with koryo. but koryo is their store brand.
Technician says there is manufacturing defect, ezone asks for technicians number, probably they will fire him for that, poor guy.
Never buy koryo products. its not worth the savings. if one product goes wrong your savings will disappear in phone calls to ezone and koryo. and that too you cant use the product for months. mine is completing one month of non use.
