Things I liked: Small, practical and easy to use because of the big flow control knob. It looks very well constructed and sturdy.
Things I would have changed: I would like to see a CGA320 to Paintball adapter included as part of the kit. The way the kit comes right now only works with a CGA320 big tank (5lb and bigger). If the adapter comes included then we can use smaller paint ball tanks (9, 12, 15 and 20 oz) to recharge the small 2.5 oz mini cylinder that the Avanti 887 uses. Other than that it's a very good filling station.
What others should know: I recommend it highy, but be advised that you need to have a bulk CO2 bottle equipped with a CGA320 connection, not the NPT used by the Paintball bottles.
