1ml Glass Dropper for SodaStream Bubly Drops, 6-Pack Pipettes Set | Food-Grade Borosilicate Glass, BPA-free, 1ml Fill Line for SodaStream, Leak-Proof Seal, Easy Clean, Color-Coded, 4.5 inch

These fit great, and I like the colors of the droppers. They have markings on the droppers that make it easy to measure how much you are adding which makes it so easy to use. Plus, they are a great price! I do recommend that you "prime" the bottle on the first use by not dipping the dropper in all the way or you will overflow the syrup. The rubber tops feel soft so I am not sure how long they will last but they do come with a cleaning brush and I expect that they will last me at least a whole year or more. For the price, if I have to replace them after every year it would be a bargain and I wouldn't feel like it is wasteful at all since it will have been used for multiple bottles. Hopefully they will make another color pack that has a few more colors in it as my collection of flavors has grown past the initial variety 6 pack I initially purchased. (Orange, Peach, Blue, etc)

Works very well!!

I recently have lost 60 pounds and part of my journey included drinking 100 ounces of water every day. I love a little flavoring in my water without artificial sweeteners. I bought the bubbly flavor drops and these droppers and it’s a perfect combo! I like these particular droppers because the tips are rounded, and they fit really well into the bubbly bottles. I had some other droppers that the tip hit the bottom and broke off!

These droppers fit the Bubly bottles well, albeit a bit wobbly at times. I love the color coded tops, particularly if the bottles are stored on the counter. Simply at a glance, you can select your flavor of choice.

I love that the colors almost match up with the bottles.

I was a little worried at first. Of course this is supposed to go w the bubly 6-pack drops set. I didn't know what to expect though I was happy to see that the pipettes are glass. The stoppers have a good seal to them; they don't leak... yet. The squishy thing on the top is big enough that it collects almost exactly 1 mL through suction. There's plenty of space between the 1 mL mark and the squishy such that fluid doesn't get into the squishy part, which prevents mold and other gross stuff. There are also 0.25 mL markings such that I can give myself a half dose or a quarter dose of I wanted a smaller drink. I have no idea how accurate the markings are. I didn't test them. A bonus was that I didn't have to waste any of the drops to make the pipette fit in out of the box. Its a close fit, and I did accidentally spill some when I first tried to screw it on. That was my own fault. Just remember to put the pipette in under suction from the squishy bit and you'll be fine. It works as intended. It's easy to use. I don't know how durable these will be, but we'll see.

These are made for Sodastream Bubly drops, so it's not like trying to repurposed something else. Use them on Bubly drop bottles, and duh .. perfect. 3-D print a little holder for the Bubly bottles that fits on your fridge shelf and you're all set.

These are large enough that you can't use them in a brand-new bottle of bubly concentrate right away, I have to keep the original lid on for a few usages to get enough liquid out of the bottle to be able to screw these on without spilling. The biggest issue is how smooth the lid on these are. If your hands are even slightly damp, it's a struggle to get enough grip on these to unscrew them. Knurling would be greatly appreciated on a future revision!
