Review (5/5): Great for Doterra OnGuard
I use one of these bottles for Doterra's OnGuard cleaner concentrate to clean my kitchen. I love it. It works great and sprays perfectly. The glass seems nice and thick.
The other bottle I use for an oil & essential oils mixture for wood polish. Seems to work fine without clogging.
Update: These bottles are pretty tough, but still no match for a 3 foot drop to my tile floor. I bought these eight months ago and I like them so much that I'm going to order another set.
