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 am 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 i like everything about these bottles except for the same exact thing i do not like about my other set of bottles the spray head rotates easily it does not unscrew that is not what i am talking about it is the spray head itself i think if the bottle was not so heavy this would not 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 wella possible solution to this might be to purchase these 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 do not have a need to order a bunch of bottles in this size enjoy the convenience of having a ready made kit of so for now i am happy enough with what i have
