I have had a Lov 21 for a few years now and remember it needing "a bit of work" but after that it shot ( and still does) quite well.

The first one I bought had to go back to the dealer as it had a bent barrel! It may have only been the plastic moulding that was bent, but when looking over the sights it was like shooting a banana !

The only problem I have had (and still get now and again) is that when fitting a new capsule it can get stuck on the puncture pin in the screw-in cap, but does not let the gas flow.

Removing the full capsule from the pin can be a bit nerve racking
