Instruct: Classify Amazon reviews into positive or negative sentiment
Query: evap evap evap.

I've bought plenty of things from amazon and never written a review. But this one I feel like I need to. I usually buy wondfo. But this time I bought these. Now I've never gotten a positive however I've had horrible evaporation lines and indentation marks that make it look positive. It's very discouraging for someone ttc. I would not recommend these. Use wondfo or babi one step.
