Received the TDS-3 meter as I open the box the meter was intact but as I try to start it it did start. I open the battery case and noticed that batteries were missing. Also the box had no 1.5V button cell batteries inside. The instructions paper indicated that batteries are including. So, to all does who are going to buy this item I suggest that you do not, because you would receive the batteries with this item. I am very disappointed, also I waited 2 weeks for it to come from abroad. I am not a happy camper. I won't buy from this seller ever again. They should of open the box to make sure the batteries were included. Also I tried to send the seller a message about the batteries and their system does work.
