Bests & Worsts Reviews from Amazon

I am a dad, trying to buy a basic pencil sharpener that works. This one does, so far. I've sharpened only 4 pencils. But I can see that this sharpener is different from others I've tried. First of all, the sharpener is weighty and substantial, which means that it has enough weight to move the pencil through the sharpener and not the other way around. Secondly, the motor is far more powerful than your average sharpener. It doesn't wheeze just to get through a single sharpening. Your pencil is sharpened in just a few seconds. Third, I can tell by the fine shavings that the blades are sharp. Fourth, it doesn't eat your pencil like other sharpeners do. It works quickly and efficiently. Fifth, it doesn't oversharpen, which inevitably leads to broken pencil points and need for more sharpening, resulting in eating the pencil beyond its usefulness. Sixth, it has a modest footprint, about 3" x 2", so I don't mind keeping it on my desk. My sole quibble is that I wish it had a plug in option. But bottom line, the sharpener works well so far. Update (12/15/16): Unlike the advertisement on Amazon, my box does not contain a "Lifetime Warranty" decal. And nowhere on the box or in writing does it make mention of that. In fact, in small writing on the User's Manual it says: "Product life: 3000 times". This is concerning. I want the lifetime warranty that was advertised. OfficePro, please send me a lifetime warranty sticker. Update (12/15/16): Spoke to customer service at Amazon. Apparently, the "Lifetime Replacement Guarantee" is an Amazon offering, and not an OfficePro offering and that the decal on the box was placed there by Amazon for advertising purposes only. Amazon assured me that they are indeed bound by the Lifetime Replacement Guarantee and expedited shipping as advertised, even though the box does not reflect that.
