Delivery took close to two weeks, product was well packed. Item came complete with an English manual. Had to go over the manual a couple of times to interpret the “China English” for understanding. The wrong cutouts template (50 85) was supplied instead of for the mortise order (22*240 / 70 85) and had to make my own adjustments! Otherwise installation was straight forward and soft setup was not too difficult. Installed and operating accordingly with good sensitivity and response. Quality seems good, hope it is durable and batteries will last for some months at least.
Lousy design...small lock... if u have previous lock installed..be prepared to see a see through hole..not recommended
