I'll start with why I gave it one star; the case doesn't allow the sound to get through adequately. You can hear people on speakerphone or other but your voice is muffled even if you're talking with your mouth right up to the microphone opening. I would not recommend this product unless it was re-designed. It's made well maybe it would be waterproof I don't know. Everything fits together well it's just the sound is awful

The KLIM keeps my laptop up to 10 Degrees cooler even during heat wave weather, in cooler weather its even more cool. I really do see the difference with this device and am very happy I purchased it. I would recommend it to any one.

Maybe just me, but I broke both screen savers in a matter of minutes trying to position them correctly on the car's screen. I've put glass screen protectors on my cell phone and tablet with no problems. Not nearly so easy with this product. I could not get the protector squared correctly, nor could I get air bubbles out once it was on the screen halfway square. I do think it would proved great protection if you're not picky about appearances.
