After my wireless mouse gave up the ghost needed a spare mouse. So first do not spend so much money and search for proper replacement .... and, replacement found! The mouse tail is great, really nice big for my paws and popped so over my desk, a real treat. So why spend a lot of money when you can have it also inexpensive really good. And branded goods, it is to (Made in China)). So I'm like many other users also excited and do not regret buying!
