5.0 out of 5 stars An Awesome Compact Keyboard, as a Backup!

I am currently writing this review with the laser keyboard. I am on my Samsung Note 8 using the Dex Station right now. i love this thing but it does come with a few quarks.
1. You will type slower, but you can actually get a pretty good pace going with this keyboard. You cant type the normal way, I use just my index fingers, this method yields a 95% accuracy when I am typing.
2. This thing does chirp with every keypress by default, but you can turn it down or silence it. I keep it on low so I have some feedback when I'm typing.
3. Going to mouse node is strange, your only indication that your in mouse mode is the keyboard dims a little. I wish 9t would turn into a mouse pad but there is no moving parts.

This is super useful for me as it takes up no space so it's easy to pack with my phone and dex station. you need a flat surface about 8" x 11" or a sheet of printer paper basically. This isn't going to be replacing a keyboard and mouse but makes an awesome compact backup. Plus its just damn

I was skeptical so I went with this less pricey one, just in case. But I was pleasantly suprised at how well it worked! Its pretty cool. My 26 yr old son, who us very "tech" minded, dug it. He had it up and running immediately after opening it. I would buy this again as a gift for sure
