While it's a very good price, it's also the same brand I've had my only SD failure with.

If you are buying the 128GB model, IMO spend $7 more instead on the UHS-II model :

Lexar 128GB Professional 1000x UHS-II SDXC LSD128CRBNA1000 B&H

While the Pentax cameras won't benefit, images - and especially videos - will transfer faster.
You do need a UHS-II reader to get the full card speed. I use this one :
Lexar Professional Workflow SR2 SDHC / SDXC UHS-II LRWSR2TBNA

While there are cheaper UHS-II readers, but I would recommend against them. I bought one from Amazon and it overheated, corrupting the data. It was sent back.

I'm sure this deal is great for those interested. I myself am a Sandisk guy

Why do the sales happen after I buy my SD cards?
