Spider Super Slim Insulin Pump Waist Pouch (Eligible for Diabetic VAT Relief in The UK)

My son (3 years old) loved this,since it had the Spiderman motif. I liked the fabric, nice and thin almost like a bathing suit kind of quality to it. It was a bit narrow even for his waistline, but at least it fit alright. My main issue is the button, with which one open and closes the pouch. This was a very poor quality, and some fabric bunched around it made the buttoning itself very clumsy. This was very bad, because it made the pump fall out quite often, and that is not what one wants with this product. The waist pouch now lies behind the sofa, and is sometimes used as a headband for fun when he's playing. It may be a good product, but when all hangs upon the pouch itself, it should be possible to make a better button for it.
