I ordered 4 pieces of this sport friend bottle for our children about 3 years ago on a Tupperware evening. Covered's Tupper lasts forever! Been wrong! The lid of this little bottle that was in use every day with us is, each 1/2 year snapped up a small tear on the feeder hole. Thus the bottles ran off again until we noticed this. Again and again cracks therefore the lids were half-yearly exchanged free of charge. What gradually rather annoyed because you always had to look for a consultant! Now today, the same re- cover the drinking hole has cracks. Now it is enough and we have all Tupper- bottles away geworfen.Und replaced by non-plastic bottles!
--Da I recommend the ALFI of bottles. Since you can even pour carbonated, which is not possible at TUPPER. And there are no toxic plastic bottles but without stainless steel contaminants, without toxins and heavy metals and 100% !!!
