Would You Buy a Refurbished or Used Keyboard?

I'm going to but a wireless keyboard. Its the Logitech K810. They're selling one certified refurbished for $50 on Amazon, one used on ebay for $55, and one new for $75. My question is, would you guys buy certified refurbished or used for a keyboard? Would you trust that?

Buying through Amazon is relatively safe, the return/refund/replacement policy is pretty good!

I would buy any refurb product. Refurb products are not necessarily defective. Some are but are already repaired and brought back to a certified "brand new" state.

I am posting right now from this computer that I bought 1 week ago:
Asus X750JA TH71Â*I7 4702HQ 2 2GHz 8GB RAM 2TB HDD HD 4600 DVD 17 3 Windows 8 1 886227843961 | eBay

It is absolutely perfect, and replaced a refurbished laptop that I bought about 6 years ago and sold a couple days ago when I got my "new" one.

I look for the words Manufacturer refurbished, though and not seller refurbished. Seller refurbished could be nothing more than they dusted it off and called it refurbishing. I also look for ads where they have/had more than 1 of the same item for sale.

I wouldn't. You don't know how it was "refurbished". I've seen refurbished PC's from one manufacturer that still had many different problems. Some were just cancelled orders and those were perfect but others had been returned because of problems or problems that couldn't be resolved. I also saw refurbs on their site selling for more than current new ones that were on sale. You don't know, you pay your $$ and take your chances. $20 more for a new keyboard is worth it to me.

When it's "Re-certified Refurb", (by manufacturer) it can be considered like brand new and comes with a warranty. If it's not like what you expected it to be, you can still return it.

I've bought refurbished devices, last was an HP Laserjet and still have it. The box had never opened. Frequently refurbished means a product with a serial number was sold, entered into a computer and cannot again be sold as new.

Agreed that is what is expected, but its not always the case. Then its the hassle (many times) of getting it replaced or a refund.
I've seen too many cases of problems with refurbs on one manufacturers forum.

In this particular case, a keyboard, I wouldn't consider the refurb'd keyboard for the $20 difference.
