Walmart sells digital TDS meters

I was looking for some bungee cords at wally world today and in the automotive department/RV isle, they are selling digital TDS meters for just $11.97! Just a heads up for anyone looking for one. They are useful for a variety of things. I don't know how the quality is, but it's a great price and almost everybody has a walmart nearby.

Drats, you post this after I just get back from walmart... Are they a wand type? I'd like to double check the TDS meter I have, that way I can have a better sense of accuracy.
