Not very 'impact resistant'
I was pleased with my purchase initially. The bottle seemed to be just what I needed for refreshment on the golf course. It looked good, was totally leak proof, felt comfortable in the hand and was easy to use. Unfortunately, on my third use, it slipped from my hand in the golf club car park and fell to the tarmac floor, whereupon it split open across the base and all the juice gushed out. So it appears that the product is not as slip proof and impact resistant as described. The lesson being: don't drop it when it's full of drink!
