Zicom is know for Electronic Survelliance Products. However, one of the Products I have been using i.e. the Video Door Phone is pathetic. The product's power unit smokes out and the product becomes completely defunct. I have replaced the unit earlier when (luckily) it was within warranty. And they mentioned that the unit is not robust and becomes defunct if their is power fluctuation. While most of the other appliances in the home are safe and sound over the years, only the Zicom Product suffers such failures. The service engineers are also pretty much aware of the problem, but the company seems to be sleeping. And, now that my warranty is over and their is no annual contract (AMC) in place (as confirmed by the Service Engineer), the company is asks for Rs. 450/- for just a visit and Rs. 2500/- to replace the unit. Who would pay Rs. 2500/- year after year for a flawed product. Needless to say, Service charge plus replacement cost comes out to be 30% of the product cost. I hope other users would take notice of this bad product quality perspective before making a purchase decision.
