Not the best product out there.
Cap fell off of one while in my vehicle.  I thought I peed myself.  Thank  God it was a faulty product.  I checked the cap and perhaps I failed to tighten it but what a mess.  I prefer the one ounce containers but those are hard to find.  I would not recommend these but if you are in a pinch and the price is right go for it.
