Review (4/5): Great alternative to glass
I really like these bottles. I've used 2 so far - one for magnesium oil spray and other for a toner. The sprayers work really well - no clogs to speak of yet.
I prefer glass bottles when working with higher concentrations of essential oils, especially citrus. However, i usually stick to 2oz or less since larger glass bottles are heavy and can be hard to grasp. I have rheumatoid arthritis and my hands dont always do what they're told. These bottles are perfect for me - they are light, easy to hold and the PET plastic is safe to use with essential oils. If i drop them, it won't be a major catastrophe - the bottle cracking is the worst case scenario. Cracking is pretty unlikely - these are sturdy bottles.
