That's brilliant John!
It might not go a huge amount lower than 1.012 but a lot of people, me included, have had these kits stick at 1.014, so it's done really well. Monitor it until all bubbles have slowed and you get the same reading 24hrs aprt, then prime a keg and rack it up!
I recommend a week in the same room that you fermented to get the carbonation going (vaseline those seals!) then four weeks (sorry!) in a cooler place.
The longer a Wherry kit conditions for the better, and the last pint is always the best.
One day, try dry hopping these kits with a muslin of aroma hops as that works really nicely too.
I have a few shiny bits here and there as an AG brewer, but my first modern kit was a Wherry and damn fine it was too. It felt no less exciting or rewarding than AG brewing.
* Here's a GREAT tip! Buy another kit and another fermenter bucket right now. Get another brew on soon and you'll be less likely to fiddle with the first one and before you know it it'll be ready and you'll be drinking that and be too busy to fiddle with the second one. Repeat until all spare storage space is full of ridiculous brewing kit and your OH worries about you...
