Easy to use. Great for security. - If you're in the market for an extra-secure lock that you can open remotely, buy this one. Ease of setup: I have zero experience with home improvement type things - I’m normally a task-rabbit girlie. But I’m currently a bit poor, so had to suck it up and install it myself, and it truly was simple to do. If I can do it, any idiot can do it. Quality: It's good. I feel like you can't go wrong with a Eufy product. They may be a bit pricier than others, but they're always good quality. They look nice, feel nice, act nice, etc. Functionality: It works. One little plus is that it works even if the batteries are dead. I was out of town and needed someone to stop by my house. The app told me that the batteries had died and I was afraid the lock would stop working and they wouldn't be able to get in. I was pleasantly surprised that that was NOT the case! One (pretty obvious) thing to note: if you have a door that kind of sticks, make sure you shut it hard / all the way. This can't lock if the deadbolt isn’t lined up with the hole in the other side of the door. App: This can be controlled remotely from the app because the lock connects to wifi. I have another Eufy lock (one of the fancier ones with the fingerprint thing - which this one does NOT have) on my front door, and that one can only be unlocked with the app if you're close enough to it on bluetooth. Which is honestly so dumb, because if I was at home when I needed to open the door I'd just walk over and unlock it manually. This one however, is a major upgrade because I can unlock it from wherever I am! Game changing for if you need to let someone in while you're not home, but you don't want to give them your code. Just unlock it for them and then re-lock it when they leave! Review: Title: Great Smart Lock – Excellent Value - This is a very good smart lock and offers great value for money. Installation was straightforward, and the app setup was simple. The keypad is responsive, and the built-in WiFi makes it convenient to control remotely without any extra hub. It works reliably and feels secure and well-built. Overall, a solid upgrade for home security at a reasonable price. Highly recommended. ## Features - Remote Control from Anywhere: With built-in Wi-Fi and no bridge required, you can effortlessly control your smart lock from anywhere using the eufy Security app. Enjoy easy setup, access management, real-time notifications, and event history. - Smart Lock: Easily open your door using a physical key, voice commands with Alexa/Google Assistant or a physical button. eufy smart lock's physical buttons offer enhanced durability and error resistance, providing greater reliability and usability than touchscreens.

It easily connected to BLUETOOTH and WiFi without fuss or problems. The Built-in WiFi is what prompted me to try this lock. It is very good.

The support assistant was extremely courteous & knowledgeable; provided the FIX over the phone, as well as by email, with a problem ticket number, in case I needed a follow-up call. I had no trouble at all following their instructions and the LOCK (eufy C30) and it's APP are working perfectly in it's new location.
