Dear Sir or Madam, 

Hi, my name is Thoven from CEN Electronics, have you ever have headache from finding keys for your lock? 

Losing Keys sucks! Not to spend your limitless talents and limited time on day-to-day finding your keys.

A fingerprint, Bluetooth, or Wifi smart padlock want you to focus your time and efforts on more significant stuffs, ranter finding keys everywhere; not worrying about pocket full of keys, or even keys scratch or damage your cloth, fancy electronic devices, ring etc.

Interested of how a a padlock works?, let's talk. I'd love to tell you more about its benefit and how we can help eliminate this headache for you.

Do you have any current issues that we can help answer?

Best Regards

Thoven Chen
