Review on Coolrunner PVC Bottle Cap Sprinkler With Little Nozzle Head For Efficient Watering Of Vegetables (Pack Of 6) by Michael Montgomery

Does what it says, and work as expected. I am using these with the Costco sparkling water bottles, and it is an almost perfect fit. As other have mentioned, it does look like little yellow plastic piece could come off over time or if trying to squeeze water out of the bottle too hard. But given the price, can't really ask too much and overall, I am pretty happy with these. The design could probably be improved, for example by adding a small O-ring inside for a better seal. Depending on the bottle used, sometimes the seal is not perfect and a drop or 2 of water can leak through. But this is really not a big deal, and definitely make my plant watering much easier. Would totally recommend these!
