Brought a Cpixen Biometric Fingerprint Password Attendance Machine on 23rd March, 2018. The product reached on 6th April. We started using the product the next day. It suddenly stopped working after 2 days. Most of the reviews mentioned that is stops working after a few days of use but still i went ahead and purchased the product. Please avoid this product as they have ZERO after sales service. Its money down the drain. You are WARNED.
