Can anyone reccomend a ground anchor? I’ve seen this one in halfrauds for 20 seems ok?

Whilst you are there take a look at their big chains. Great company to deal with. I’ve bought a shed shackle, ground anchor, chain and lock from them. They’ve always been exceptionally helpful.

Their ground anchor is very good, as are their chains. Very helpful as well.
