Hello friends, Today I share my experience on Crusaders Air Purifier XJ -3800-1. I buy this product after few days ago. After some days its create problem like not filter the air .The layers of Air Purifier is not working properly. The switchs are very hard to handle. This is very difficult to use. Its not a user friendly product. It’s not durable product because its problems rise repeatedly. The style of this product is very poor. I don’t like the design of this product. Their customer service is not reraible for me because they attend the service call after two days. My view of point this is not good product.
