I came across with a BLW set recently that has very strong suction power, and it still sticks pretty well so far. It's called yooforea BLW set if you're interested in trying out. I got it from Amazon https://www.amazon.com/Yooforea-Silicone-Training-Toddlers-Dishwasher/dp/B096DBSCZL?ref_=ast_sto_dp&th=1.
