Really useful bottles
Having just done a review of the wide mouth replacement lids (that you suck through rather than pour) felt it necessary to review the bottles themselves. Bought my first pair at Costco and they were so so useful tried to get two more but Costco don't do then now so tried and succeded with Amazon UK. More robust than plastic bottles and keep the water really cool. I use my for squash as plain water not to my liking but you do need to wash out bottle and lid frequently as the squash can leave residue which will tiant the taste, especially black currant and apple.

Hits the spot
Bought this for my son to take to school, we have been using on trips outside home all summer. I took off the straw, and it works perfectly well and maintains the temperature for a good 5-6 hours. Easy to clean, easy to use and the lids are interchangeable. What’s not to like!

Does not keep hot water hot
Hot water goes cold in about 3 hrs

Here's another version: I'm really impressed with the ThermoFlask Double Wall Vacuum Insulated bottles! They keep drinks hot or cold for hours, and the double pack is a fantastic value. The design is sleek, and they're easy to clean. Perfect for work, hiking, or just daily use. Great product!

muy buenos termos. duran mucho. el protector de goma es un game changer. sin el. sigue siendo 100% útil nada mas que estéticamente se ven muy avollados y suenan más duro cuando se caen. Yo sólo los uso para agua al tiempo / fría y conservan muy bien la temperatura. claro que depende de la temperatura ambiente, pero si es un ambiente templado, hielos me han durado más de 24 hrs. En climas muy cálidos de más de 30ºC, si duran a lo mucho un par de horas. AMO ESTOS TERMOSSSS <3

The bottles were delivered in good condition. I had a set of such bottles; however, their size was a bit smaller. Size of these two bottles fits our requirements and expectations. Also the cap is very friendly and easy to use.
