I have a few rental properties that need humidity controlled and have a few of the older models of this. The lock controls are great on this model. I purchased the new version of this that doesn't have wifi, but it didn't have the lock control and I returned it and got this one. I need the lock control so people don't change the settings. I didn't think I wanted the wifi feature, which is why I originally purchased the other version, but the wifi is actually pretty useful. I wish the integration with Google Home had more features other than being able to turn it on and off through Google Home, but the Frigidaire app has all of the features and works well. This is definitely a great product and works great especially with the continuous draining so I don't have to deal with emptying the water.
