These locks do exactly what they are supposed to when they are in working order. However, in my experience, a working lock is hard to find. I ordered 3 locks in October 2017. One was defective out of the box. I sent it back and received another within a few days. Last week (Sept 2018), one of them malfunctioned- not properly locking and unlocking, seems like a motor issue inside the lock. Customer support walked me through the troubleshooting steps and said they would need to send me a new one. If it's in stock, it should arrive in 10-14 business day. If it's not in stock, it will take 4-6 weeks. But, of course, you can pay more for expedited shipping! Just my luck, my replacement is not in stock so I have to wait 4-6 weeks before I can properly lock my home again. Would not buy another and would not recommend.

Works Well if Not Defective (but apparently that's asking a lot) - Disappointing Warranty Program
