I had one in .177 and .22 (but no more):

- Comfortable weight and balance
- Chunky anatomical grip is rather good
- Single pump is good for short range targets. Very easy cocking effort
- Two pumps is optimum for longer range targets. Moderate cocking effort
- On some variants the front sight rotates to help with the point of aim (for different pumps)
- Three pumps is pointless (too much effort for little gain)
- Multiple trigger adjustments are effective.

Things I did not like (on both calibres):
- Takes a couple of shots to get the trigger to settle in at the start of every shooting session (if you look at the internal 'cast alloy' parts you will understand why it could be somewhat variable).
- Spare seals are not listed by Chambers, only the entire valve and cylinder are listed (£120 plus post last time I looked ).

Worthwhile at a bargain used price The brand new price gives one year warranty on the guts/seals..
.then you are on your own
