A no-nonsense well written coaching manual with plenty of easy to understand (and thus easy to explain to 13 and 14 year olds) drills and activities. This is not a magic silver bullet but a comprehensive reference book, use it and it will reward you and your players
My old blade was a real cast iron fitting and battered it's way through anything our garden could throw at it. This replacement is a thin, flimsy sheet-metal type and although okay when cutting ornamental lawn grass it just got distorted when it "nicked" the remains of an old shrub stump. Totally written off in its first use.
My old/original hose trolley had long since been wrecked my my own mis-use!! This Compact Reel is much more sturdy (sturdier?) and easily winds in the hose and also has one of those clever little widgets that allows you to conncet the whole thing to a water supply via a small transition piece.
Once fully charged it lasts for more than 2 hours - continual use.
I have no hesitation in recommending this battery as it is a genuine part (and with so many non-genuine items out there in cyber market place) it really does the job expected of it. Unlike many of the "copies" being sold - read their reviews and find out just how disappointing they are.
