Vortex Bottle connectors

Great entertainment for my autistic grandson.  They keep him busy watching the water spin around and around like a tornado.  Other similar products are self-contained and break easily making them an expensive item to replace.  However, the connectors are used by attaching them to two large pop bottles.  If the pop bottles break, the connectors are removed to put on two more bottles at no expense.  Thanks.

A good collection of Dupont connectors, but why no 2x2's?

Very nice glass bottles, tiny for essential oil mixtures and the sprayers are well made, fit snugly, and spray a fine mist. For a very low cost I have exactly what I need. I also like the cobalt blue glass. It is necessary to protect oils from light.
I will buy again.

These are great bottles, w/standard caps, bought and used for DIY E-liquid ingredients.

By far, the best price I could find on these items and will be buying more as needed.

This cleverly designed and well manufactured mount can be used with any bottle cage that has the standard attachment spacing.  The stainless steel band that grips the mount to the handlebar or seat post is initially adjustable to three lengths to fit nearly any handlebar diameter.  The adjustment is accomplished by selecting one of three holes in the strap.  Then, as you torque the tightening bolt it pulls the strap up into the base unit making the attachment very secure.  When properly installed it is extremely unlikely that any bottle will cause the mount to change location on the handlebar.  The plastic is precision molded and while I do not doubt other's experience of braking this mount I suspect there was quite a bid of force involved.

Sturdy and lid closes tight.  When the spout is removed the female threads accommodate standard PVC 1" plumbing fittings with male threads.  I could convert the spout to an icemaker line with a small ball valve and use this as a drip system to top off my salt water fish tank by gravity feed.  But note that you can do the same to fill a coffee maker, drip water plants, etc.  The standard thread makes the product very versatile for DIY uses!

Nice quality, but they don't fit into the LeRoux balsamic vinegar bottles, which is what I bought them for. The bottle is a common size, but they will not snap the thread into place and it falls out. Dissapointed.

Also purchased these for storing photo chemicals. It's very hard to find brown glass or plastic bottles in 1-liter size. These seem very well made and I would feel confident also using them for homebrew beer.
One thing to be aware of, the caps are the locking type, similar to commercial beverage bottles. When you remove the cap, a plastic ring is left on the neck of the bottle. If you don't want that, you should remove the locking ring from the cap before screwing it on. Otherwise, the caps seem sturdy enough for re-use.

The color is wonderful.  They fit the flask nicely too.  I use them when I don't want to just use the loop from the lid to hang onto my water bottle.

Good quality. Connector halves fit together tightly. Have not tested water resistance, but I believe they'll be adequate for anything other than harsh conditions. Connectors rely on friction and plastic tension to stay together, so I would probably not use them in applications that require repeated connection & disconnection due to material fatigue after numerous connections. Great for staying connected with occasional separation.

Please see my review of the Dramm 12353 Heavy-Duty Brass Shut-Off Valve where I describe in detail the pros and cons of these brass fittings.  Despite the minor cons, I ordered a second set for another area of my property because these are heavy duty quality connectors.  If the female quick connect came with 2 extra DGHW7 rubber seals I would give this connector 5 stars.

I absolutely love the Porter Cable Forstner bits. They work well for the Vapor caddies I build custom for Vapor shops, and I build custom vapor caddies also!

Universal, reusable caps--these work perfectly for bottles that you're refilling for use at a water cooler.

I bought these as replacement caps for oils, liquid vitamin and tincture bottles. They originally came with dropper style lids. I have found that the rubber of dropper lids often degrades and contaminated the liquid. Have searched for the right size replacement caps for awhile. These are perfect. I recommend them for anyone who has dropper bottles. Replace the caps and only use the dropper when you are using the product.

Nicely manufactured bottles and glass droppers. The tips of the droppers are now protected in shipment by rubber o-rings. All of mine arrived intact. The rubber squeeze bulbs work well and create a one-piece seal for the lids. But bulb capacity is a little small and will only draw fluid up about a third of the dropper. Fine for very small amounts, but not if you're hoping to pull 4-5 ml at a time. So, I dropped one star for the rather small capacity bulb.

Very nice little bands to help add style and personality to your Hydro Flask.  This bands fit the standard lid (not the straw type or the flip top) replacing the standard grey colored one that comes with the bottle.  If you have one of the other lids you can put one of these around the actual bottle, would be especially helpful in keeping it unique and not getting it mixed up with another bottle of the same color.  Little pricey considering they are similar to a rubber band, but they serve a purpose.

These quick connectors are awesome. It sure made my life easier. It's so easy to change out the hand-held sprayers or move the hoses. No more trying to screw a hose to a faucet, sprayer, or another hose. I have ordered these last year and ordered more this year. They held up well and do not leak. Very satisfied with the purchases.
