Excellent products. Bought a 800ml bottle with straw cap for my daughter to take away on a school trip. She is delighted with it and now takes it to school daily. Fantastic that you can buy a replacement cap too as someone knocked the bottle off the desk in school and cap broke but a replacement arrived the next day after ordering. We bought the colour milk but I think more variety of colour choices in the 800ml size would be good as I preferred the colour choices in the smaller sizes. Quality product. Most important: leakproof. Am tempted to buy myself one!
