I've been using the 223 and 9mm oil vial for the last 9 months (I keep the 9mm on my wife's key chain so if we're traveling in her car I still have oil on me at all times) and have had no issues. They hold oil and look great. I also get a lot of comments about them and people love that it's an oil vial. Also gives you a great opportunity to teach non-members about the priesthood when the inquire about the bullet on your key chain. I've had no experience with the spirit leaving or feeling a lack of priesthood power when using these oil vials.
