Easy to use and seems comparable to others I have ...
This is my first go at using 02 drops, so I don't have much to compare it with. Easy to use and seems comparable to others I have seen on the market. I am seeing a minor pick up in energy and less muscle pain. That sometimes ebbs and flows, so I plan on adjusting this review if the improvement continues.  As a disclaimer, I did receive this item for a discount in exchange for my honest and unbiased review. I do the bulk of my shopping on Amazon as I don't drive, and I too rely on reviews to make informed purchases. I do not give out four or five stars easily and am in no way obligated or influenced to leave a positive review. Happy to answer questions
