I bought this product based on the reviews here and did not regret. The bag has some Verstaufächer, which are very useful. The mobile phone pocket is too small, I can not agree. A Samsung Galaxy S2 fits easily with envelope in the tray. The cooling stops at things that previously were in the fridge with ice packs for 24 hours. I have 6 ice packs used: below 2, side 2, the top 2. I highly recommend this bag to anyone.
