Product Info: I purchased the contact companion because I travel every week and needed something compact yet functional to carry my contacts. I got tired of lugging around my big bottle of solution so the 2 bottles that are included in this product is great for that. They are color coded so you can put different solutions in each. The tweezers are easy to use and I am paranoid about infection so I love using the tweezers. If you are like me and use a lot of solution (disinfect case, new solution every night) then you might need more solution than can fit in the 2 bottles. If I am going to be away for more than 3 days I usually bring a travel size bottle of contact solution. Also, if you use your own case it might not fit, but theirs is perfectly fine. But it is a really great product and I am always using it. I would recommend it to frequent travelers or even if you just want it to keep in your purse. It's cute and small!
