Review on Bottiful Home - 2 Twist-On Plastic Funnel Set for Easy 🏠 Household Use - Compatible with Various Bottles - Hands-Free, Food-Safe, and Durable by Jennifer Collins

I needed a funnel to fill hand sanitizer bottles. I thought this seemed like a great idea and now that I've used it I'm so glad I got it. I have two different sized holes and I didn't even know they would fit both. Wonderful. When it's tight it doesn't go through the funnel well, but when the funnel is full I loosen it a bit and then it has the air gap it needs. I also tightened it so that it was secured but not as tight and full which worked well as long as I knew it would hold up a lot more, but once it was closer to the fill I liked my first method. I highly recommend this product.
