Freestyle works much better than 2 Swing. It's really trouble to operate 2 Swing unless you have a very good place for you to do the pumping. You can imagine how trouble it is if you have to use 2 Swings to pump milk in a washroom. The suction of Freestyle is much better too. At the very beginning, I used 2 Swings to pump milk and later changed to Freestyle. I can finish the pumping in 10 min. with more milk.
I don't know how's Swing works. I use Mini Electric before. Freestyle is really much much much better.
I bought Freestyle from the web and shipped from the States.
The pump: US$299
Shipping cost: US$69
It takes around 4 days to ship from the states to HK.
But the shop was out of stock at the time I order, he claimed that there was a sudden increase in demand of the pump. I had to wait for 2 weeks.
I think HK dealer is setting the price far too high. I don't think deal will keep many stock as I think not many people will buy the pump at HK$5200.
