Review (4/5): Very leak-proof
Overall, product works well. Containers are leak-proof, easy to squeeze. Contents do come out as a thin jet, but it's not too hard to control and is a fair trade-off for the leak protection.
Docking one star though, because one bottle was so leak-proof it didn't have a dispenser hole cut, so I had to poke one in it myself. Not a hard fix, but maybe production could use a bit more polish.
