Very Bad Service - Stay away from Mustek / Mecer products

I bought a new Mecer inverter and on installation, I am getting an error code 09 which is an internal error. I took it back the day after I purchase it. The supplier then said that they have to send it back to Mecer/Mustek. It will take 10 days before I will have an answer. Really? Selling a faulty product then I must wait 10 days for replacement!! Think twice before you buy a Mecer inverter ...... I think, that when selling a faulty product that the client deserves an immediate replacement. Today is already 10 days and no repsonse yet from Mustek. I will never buy any products that are supp**** by Mustek. Stay away people there is enough good suppliers in South Africa we can support.
