Quill is owned by Staples & many items are shipped on Staples truck. I placed an order with Quill. I have used both before & will continue to do so. They asked for a review of a Logitech K350 Keyboard order & I gave it but 3 times I tried to submit the review without success so if this goes through, here is the unbiased, actual review.

**Replacing 7+ year old Logitech K350 Wave keyboard with same. Old keyboard keys are sticky & covering on palm rest tearing off. No matter how good the keyboard, without a good Unifying Receiver & without the receiver I already had, I would have returned the keyboard as nonfunctional. Like the keyboard & M510 mouse--hate the new Unifying receiver.

**The OLD Unifying receiver which I already had WILL pair with & work with the old keyboard, the new keyboard, my M510 mouse & another mouse. Remove Old receiver & all disappear from under devices. The New Unifying receiver will NOT pair with the Old keyboard or M510 Mouse. The New receiver does show under Devices as does the New keyboard but the New keyboard will NOT work with the New receiver. Remove the New receiver & both the receiver & New keyboard disappear from under Devices so I guest the keyboard is paired but it does not work with the New receiver.
