Bests & Worsts Reviews from Amazon

I rarely write really bad reviews but this particular product and seller irks me the wrong way. Let me get this eye brow raising bit out of the way first: Under Amazon's My Account/Your Orders, this particular product out of hundreds of other products I have purchased is missing " Leave Seller Feedback" and " Write a Product Review"...among others. I WONDER WHY? Let's talk about the actual keyboard that I purchased for ~$17.00 on August 25, 2018. The date today is October 13, 2018 and already the ENTER Key and the Left SHIFT Key have failed. Meaning, pressing those keys will NOT preform a desired action, ever. It was a gradual but quick failure ( 2 days). Ohh, It's a pretty looking Keyboard but underneath the skin it's full of nasty surprises. The last time I checked, the entire premise of buying a KEYboard is when you press a KEY, it will preform a action. That is its primary function. Really, other than slight ergonomics and how they (KEYS) 'feel', NOTHING else really matters! In the matter of less than Two Months, 2 of the most essential keys required have already failed! I am not the first or last person to complain about this. Do not buy this product and stay away from this seller. Just my opinion.
