My 2 year old son is huge Thomas fan. This DVD has long introductions to each story in which children and adults are interviewed - my son couldn't care less. He just wants to see trains! We have a portable DVD player, and it is a big pain to try to fast forward past these introductions, and he (and I) just ends up frustrated. My advice - pick another DVD.

I have always had trouble finding the perfect toner for my skin type. I have oily skin but it is also extremely sensitve to burning and tingly toners that contain alcohol in the ingredients. I have tried a lot of toners, and this is truly one of the best ones I have ever used IMO. It is very gentle and does not produce a burning or tingly sensation after application. It has a great, light, clean scent and does an effective job of wiping away any remaining oils/dirt on your face. I like to use it after cleansing and prior to any day/night moisturizers.

The bed is nice and soft and double thick. The auto pump is easy to use and works pretty well with new batteries. The vacuum drain does ok but when down to the base have to help it by rolling it at the end. Folding it isn't to hard and package size isn't to big so easy to store. Bed lines fit ok on it but get good one so they squeeze tight so they hang on. But for the money is a great buy I shopped around a lot target, walmart, dicks, Meijer, sears, kmart, ect. So very good buy if you want one for camping or a guest bed.
