Quality of this product hasdeclined
Updated review. I ordered 3 additional level indicators nand 2 did not work. Seller quickly  sent 2 replacements but 1 did not work. Between the 5 I got 3 to work. by replacing batteries and moving the leads. I ordered 3 of these items several years ago and one is still working. The quality of the recently sent indicators is poor and some of the batteries were installed wrong and some were dead. I use and rely on these little jewels everyday. I fear That I may need to find another level indicator brand that maintains product quality.
