Took out from package, looked at instructions (seem easy enough), installed app, plugged into outlet, followed the instructions, and every time it tries to "find device" after connecting to the device's wifi, it gives the error "device not found" and can't proceed with the install. Completely useless. Find a better brand of smart plug.

I bought several of these because of the great price. I spent well over an hour trying to get one of them to work and was unsuccessful. I checked the Apple App Store reviews and found that the app is rated 1.7 out of 5 stars with many saying that they too had extreme difficulty getting them to work. We took them all back. By the way, I have several smart outlets by a different manufacturer and they set up quickly and easily.

Only the manual switch works after two weeks. Wi-Fi functions does not operate app doesn’t work only the manual switch on the side of the unit works. My advice if you want something that works don’t buy this unit as the Upgrades don’t function either. The other negative reviews are very accurate in saying find a different product this one is not worth the time and effort to make it even tried to function.

If all you want to do it turn a light off/on with your smartphone, these are fine. If you want to use them to schedule a time for a light to come on this is not the device. I have two of these and the schedule worked for 2 days on each and hasn't worked since. No support from Capstone.

Unable to reset password. System not accepting input.

IMO, was easy to install. Using to monitor energy use of a humidifier and a sump pump. I don’t have a need to integrate with Alexa. Satisfied!

These work great! I followed the instructions and was able to get two lamps set up. Nice feature. My husband even tried turning them on from about five miles away and it worked! He has them set up on his phone too.

These were great for about 6 months. We used them all the time. Now, they won’t connect to Amazon Alexa and the skill to use them has been completely deleted. We can still use them through the capstone app but that’s not why we bought them.

These have absolutely no reliability what so ever. Continuously loose connection and need to be reconnected. TOTAL GARBAGE!! Software is a Joke. Alexa skills not supported

I’ve had these for years but rarely use them. They are no longer supported by app so the only thing they do is take up space. You can NOT connect to any device to control them! Seller should pull and not be allowed to sell!
