Excellent investment! – I use this pump religiously whether it's at home or away on holiday. I've had it for 3.5 years now and it's still going strong, so it is definitely an excellent investment and worth every penny. Currently with my second Bub I have been expressing 2-3 times a day and have a good freezer stash, easily expressing upto 160ml per boob (sometimes over 200ml on the overacheiving boob). Very quiet and comfortable to use either with single or double option. Highly recommend if you're looking at a good quality and long lasting pump.
