Review: Worked well until rabbit chewed it :( - This product worked as expected but comes with a tale of woe. So I bought an hp desktop from my mom and put it in my room. Excited, I was, to play Minecraft, work on school, and even watch Netflix. Unfortunately, within the week my pet rabbit (her name is Zara) found a way behind my desk and chewed the cord of my new computer in half. I was, as could be expected, frustrated. But I simply went online to find a replacement charger. I made my purchase from a cite called AC Batteries. Every time I looked at the desktop, taking up my whole desk, I remembered what was on the way. Except days upon days were going by… One day it dawned on me that it had been three weeks. So I emailed the company and without a response I grew suspicious enough to look up the site. A scam. I had been scammed gosh dang it. Fine. Whatever. It was probably poor judgment on my part and there’s nothing I could do to get my money back. I will go on good ol’ desertcart. Reliable, affordable I should have done gone here straight after my bunny chewed the cord. So I bought this product and within the week was able to reunite with my long unused computer. That night my dear long eared Zara was in a play pen in my room. She had her litter box and water and hay and toys and blankets. I was peacefully getting ready for bed. Somehow Zara managed to push the fence and slip out. Freedom!!! She made a beeline for my desk and as I rushed towards her… One little bite was all it took with those sharp teeth. The new cord was beyond function, beyond use. I am currently deciding to give up. My hopes and dreams, visions of minecraft and YouTube, died in a graveyard of mangled phone chargers, computer cables, lamp cords, and even a heated blanket. The moral of this story is that rabbits are evil creatures and that writing reviews on desertcart may just be the therapy I need to move on. Thanks if you read this review:) I really do recommend such computer cord!
