• •The shelf life is only 3 years, which is a bit shorter than I'd like.
• •The manufacturer is China, which might be a turn-off for some people.
• •The price can vary wildly depending on where you buy it, which is annoying.
• •It's not as strong as I'd like it to be, so you might need to reapply frequently.
