These seemed so good - plastic free, dishwasher and heat safe, unbreakable, stick to the highchair tray (but not the countertops), but too good to be true after all. After months of use it's become apparent that they taint warm food with a nasty taste. We altered our cleaning to see if that was the problem but no luck. It's horrible and I feel so guilty. I hope it hasn't done any damage to my baby.
