Review title is Beautiful Upgrade for DIY from Polluting Plastic Bottles [SEP] This is the second set of spray bottles of this type that I have ordered. Each set has been from a different brand/seller. They both perform exactly the same. I use them to make my own household cleaners, room sprays, toilet sprays, etc. I'm not a fan of our cultures plastic addiction & try to reduce my impact on the planet when I can. Running my own eco family farm full time helps considerably ;)<br /><br />I like everything about these bottles except for the same exact thing I don't like about my other set of bottles, the spray head rotates easily. It doesn't unscrew, that's not what I'm talking about. It's the spray head itself. I think if the bottle wasn't so heavy this wouldn't be an issue, but when spraying downward, the bottle will move due to the weight. If I hold the bottle with one hand, while spraying with the other, all is well.<br /><br />A possible solution to this might be to purchase these 16 oz amber glass bottles separately, then purchase a separate pack of very highly rated, top quality spray nozzles & a sheet of labels to see if that helps. Perhaps these sets are being sold with lower quality spray nozzles. I really cannot say. I currently don't have a need to order a bunch of bottles in this size & enjoy the convenience of having a ready made kit of 2, so for now, I'm happy enough with what I have.
