Received this product used 2x times now.

I purchased this product and returned it because I received it used with the PH 4 and 7 bottles used up to as they were different levels of fullness but claims to be 2 oz each. Also the actual measurement device was used too with water droplets inside the plastic case. I sent it back and received it for the 2nd time and received it used again. I mean if you're going to send us new ones at least be smart about it and dry it out. Seriously????
