Hi @makinwa, This seems a very interesting hunt. Below is my review:

Pros:

i. This is a keyless lock
ii. It has a solar battery that lasts for 3 months
iii. In case of emergency, Deeper Lock is fitted with a micro USB port. This port will work with any standard phone charger or power bank.
iv. Deeper Lock is compatible with almost all IOS with Bluetooth 4.0 hardware and are running on iOS 9.0 or later, and Android devices that have Bluetooth 4.0 hardware and are running on 4.4 or later.
v. The lock comes up with a limited 1 year warranty.

Cons:

I have seen several locks and I think this lock is a ray of hope in the theft environment. Seems perfect. No cons.

Impressive hunt!
