Useful but several leaks - Update, 5* customer service
on 12 February 2012
I can't offer a comparison with other storage bags as these are the only ones I have tried. I was swayed to buy them by the good reviews and have certainly found they have several good points. They freeze nice and flat, I actually find I am saving quite a lot of milk because I bought them. The VIA storage pots with the Philips pumps are really not convenient for storage of milk in comparison. I have seen that they can also be used for purees when weaning so don't need to worry if I have any left over. The writing tag is useful as even biro works on it (though it is upside down to my mind). The double seal definitely doesn't leak BUT I've had bags which have split at the seam and another at the base where there is no seam whilst I've been trying to defrost them, even laid flat on a plate of water! I don't know if this is due to the expansion of the milk when you freeze it as you are told to remove as much air from the bag as possible to prevent freezer burn. Maybe removal of too much air means the bag can't cope with the expansion well. Whatever the problem, I am a bit disappointed and will be trying other brands for myself when these run out.
Update - I reported the leaks to Lansinoh and had a reply stating that the bags can quite fragile due to the use of virgin plastic which can become brittle upon freezing, but that I may have had a faulty batch (the batch number has been reported). They have recommended freezing the bags with a piece of kitchen roll to protect them from sticking to the shelf or each other and have sent me some bags so I can double bag the ones already frozen when I defrost them so the milk can leak into something sterile if the bag leaks and not be wasted. The customer service was superb and I would now consider buying these bags again, though I have also bought 10 Philips Avent cups.
