they're alright. I certainly have some in my bag at all times. they are convenient as they are easily accessed for most and in plastic. All of my other remedies are in glass which isn't as easy to toss in a bag and head to a playground. Plus my kids carry remedies on them and it's far easier to give them a plastic tube that has a dispenser than a glass vial that doesn't!
If I were placing a special order or getting a kit I'd go with one of the other labs though. Dolisos also comes in plastic and has a dispenser and I like them better than Boiron.
I will admit to a prejudice to the #10's vs the #30's (though different manufacturers have different sizes.)
