Broke after first use

The nuts holding the air ducts broke after first use. Knowing it was probably very cheap plastic, I tried not to overtighten it, but it didn't matter.

Pros
  • Acceptable
Cons
  • Many

Good but it's starting to fail

I've been using it for about 3 months now. The top of the cap is beginning to separate from the sides. The o-ring inside still holds pressure, but I'm not sure how long it will last. At least it comes with two and I only use the one bottle system.

Pros
  • Excellent design
Cons
  • Functionality

Great for 2 liter shrimp hatcheries!

These things are amazing! I use them to start Artemia incubators from 2 liter bottles! They are very high quality! Absolutely, 2 liter bottles are perfect here! Trust my rating, it's correct! You will be glad you bought them! I've been using this stuff for over 30 years and I'm telling you it's the best I've ever found! Oh my god I don't understand how ANYONE could give them a bad review! Maybe the person who said they didn't fit tried using them on a 50 gallon drum! lol!

Pros
  • I cross my thumbs
Cons
  • Weak set
