Must be my brother. LOL Sorry but my bro never uses a meter and can't figure why things go good then go very bad and then good. I gave him a meter and things went so well till he dropped it in the water. He saw how important it was and is still tooooo cheap to buy another. Sooo sad.

Here is the one I gave him. I get them 4 or 5 at a time because of friends and just to have on hand.
