BUYER BEWARE: Stores merchandise may HARM or KILL YOUR PET!!!!!!!!Last week I dropped into Petlands Discounts to purchase a vacation feeder for my fish tank. I told the clerk my tank specifications, number of fish etc. She recommended three different products. I told her this was my first time using a vacation feeder and specifically asked for the best product (I love my fish!). She picked out a Pure Balance Vacation Feeder. I followed the directions for this product and left on vacation. When I returned home two of my beloved fish were dead (and covered in white substance). On Amazon this product has 3/5 stars, and was given 1 star by 45% of reviewers who report similar problems. For the life of me I cant understand why the clerk would not warn me that this (overpriced) piece of garbage might kill my fish. SAVE YOUR MONEY. SAVE YOUR FISH. SHOP ON AMAZON.
