## Description

desertcart.com: ProtoArc Ergonomic Foldable Keyboard, XK03 Split Folding Travel Bluetooth Keyboard, Ultra Slim, Portable for iPad, iPhone, Tablet, Laptop, PC : Electronics

Review: Best keyboard! - This is the best keyboard i've used possibly ever? It folds nice and flat, so easy to set aside if I need my desk space. it's more comfortable to type as well. The only drawback would be if you have a PC and not a Mac (I have a mac). I haven't had any issues with bluetooth connectivity or battery dying either. The charge actually lasts a long time, and I don't even know how long because I charge it every couple of weeks to make sure it doesn't run out of charge while I'm using it.
Review: Great travel keyboard - I bought this as a travel gift for my partner and he absolutely loves it. It’s sturdy when unfolded and has a nice feel on the keys. Soft touch and high quality. The carrying bag is great. It folds right up into a backpack.
