I apologize for not answering your question in my previous post.

No I don't have any experience with their pH or TDS pens. But as far as the inexpensive ones go they all likely come from one of a few factories and are basically the same. If you're talking about the $15 pens I wouldn't buy one of those throw away pens regardless of brand. I'd use drops before one of those. They do have a unit with a replaceable probe but it's significantly higher in price. I might look at one of those if I was in the market.

Sorry I caused you thread to go south.
