The SKIP2 is their outgoing model, which has recently been superseded by the SKIP3 (which is $499 new).
Only potentially real-world differences I can see from a quick look are:
- Basket: 2 = 5kg, 3 = 8kg
- Seat capacity: 2 = 20kg, 3 = 22kg
- Weight: 2 = 6.9kg, 3 = 6.6kg
The rest looks pretty similar for all intents and purposes. Comes with a carry-handle and cover for airports etc.
Accessories are also 30% off, including an organiser, UPF screen and foot-warmer.
Price doesn't include shipping, was $20 for me to outer-city.
Excellent find OP at this price especially as it is close to used prices and comes with warranty.
