Keywin U-Groove Multi Wireless Bluetooth with Touchpad Keyboard, Double Channel Design Full Function Keyboard, BT 3.0 ,Universal for Ipad Air Mini,Mac,Laptop,Ipad and Tablets PC Multi-Device (Black)

I purchased this and connect to two devices. The setup was easy, and it works seamlessly between the two devices for 10 days. The battery lasted a full week of office and smart phone use. The only things I didn't prefer was the toggle switch that switched between the two devices. I would prefer it was a soft switch so I didn't have to use my nail. It took exactly 2 seconds to switch from one device to the next which I would take a sip of water and be ready to go.

Second one of these I've purchased (one for work and one for home). Love it. Super easy to connect and the mouse pad feature is a big plus for me.Only have to charge every week or so and uses a micro usb to do so

After only a month the battery no longer charges. Also, when it did charge properly the battery would still die quickly even when it was turned off. Also, the track pad was very non-responsive and virtually unusable.

and, that doesn't happen too often.My wife really likes the change back to a full-size keyboard. She uses it with iPad, KIndle Fire, even saw her drop in her phone. I think the U-channel is a brilliant idea.

Ended up buying another because this one was just not right.

The keyboard is useful. I like having the built-in tray to hold the iPad and my phone, as well as the ability to switch between the two with the keyboard. And the number pad works well when crunching a lot of numbers. There are two issues that detract from the keyboard's usefulness. First, the touch pad is not compatible with an iPad. This was disappointing. The second issue is one that has been mentioned in other comments: the enter button is placed in such a manner that it is pretty common to hit the backslash key by mistake. As long as you can deal with these two issues, the keyboard is a pretty good choice.

Excellent for my iPad Pro 2017
