I purchased the item and received it on time. However, it was DOA. I've tried three different computers, about 8 USB ports, used freshly purchased alkaline batteries, pushed every button on the mouse, but it will not respond. The laser on the bottom will not light up, even though the LED button on top which says \"CPI\" does come on briefly.<br /><br />I wrote to Sharkk and explained that it was DOA - the laser would not light up. Their initial response was strange - \"The mouse that you have is an optical mouse so there is no light underneath.\" Eh?! An optical mouse uses laser light to track instead of a track ball. Their second message was asking if I'd clicked the mouse. I don't want to ding them unnecessarily, but of course I clicked the mouse. Would they really suspect that I'd put the batteries in and then just move it around without clicking?<br /><br />I've had several emails back and forth from the customer service department, but thus far - two full weeks after the item was delivered - I do not have a working mouse.<br /><br />I'm confident that the company will make this right, as they appear to take great pains to offer excellent customer service. Once this issue is resolved, I'll update my rating. I have other Sharkk products and am very happy with them.<br /><br />UPDATE: My confidence in the company was undeserved. After our last round of email, I never heard from them again. That's too bad, I really thought they'd come through. To reiterate, the mouse was DOA, I informed the company, they emailed me a question which I answered, they emailed me another question which I answered, and I did not hear back from them. I emailed them again just in case my last email got lost somehow, but never received a response. I addition, they have not responded to this review like they have others.
Output:
Negative Review
