If you are a plant or flower connoisseur, or somebody trying their hand at becoming a green thumb enthusiast, this is a must-have product. It is certainly something I wished I would’ve known about a year ago. I grow succulents, I grow herbs, I grow ferns, I grow so many different types of plants and little baby indoor trees and indoor plants & fairy gardens, and this makes things so clean and pristine and when you you use a large watering pot to water all your plants & flowers, you tend to make a mess — similarly to when you have a fairy garden with live plants or even a terrarium., you really need something just like this. Two green thumbs up ... way up!! 🌿👍🌿👍 This is the largest size I have thus far and I don’t think I need anything any larger. Great product, well worth the money. Must buy!

I got this to dispense a small amount of alcohol for cleaning the print bed of a 3D printer. It works great and i still have alcohol in the bottle after it has been sitting for a long while. Makes it easy to dispense a small amount. You will see improved prints and bed adhesion with a clean print bed.

Excellent value. I use these to top up water levels for my water propagation tubes and succulents around the house. I would test each unit to make sure it sprays water straight - if not, you'll need to trim the nozzle ever so slightly to remove any debris left over from production as half of my bottles would spray 10-15 degrees to the side. Water pressure is good. I can spray a steady stream accurately from two feet away, and up close the bottles have a good flushing power equal to that of how much pressure you place on the bottle. Left in warm sunlight will cause the plastic to yellow (but does not affect the usage, they're just as pliable and durable as the ones that were not left in sunlight over the summar) The top nozzle is a little brittle, I broke one of the larger bottles when it dropped off my kitchen counter (empty) and landed directly on the bend, causing the nozzle to snap off at the base of the lid.
