I've been using them for about a year and to be honest they're not bad. If I squeeze the eyedropper twice, it fills up completely. They're pretty durable. I've lost my fair share, busted maybe 2 in a year. I mean, Ice actually dropped these things 4 feet on the sidewalk and didn't break. Strong little suction cups. There was no leakage problem at any constant speed. The rubber lasts a long time. A few melted over high heat. Getting hands on melted rubber is uncomfortable. It's really like resin. I mean... a parked post office hidden in direct sunlight on a Las Vegas summer afternoon. So you should be fine. I would recommend. I hope they don't raise the price because I gave them a good review lol. I like them for that price.
