My parweld cost less and has been spot on.Just had a look at the item on the screwfix website. Single arc sensor isn't the bes, at least a couple will be better. It also says 'solar powered' So that could mean it has no batteries in it. It also has no shade control which isn't good. For the price, you may as well get a lidl/aldi one
Thanks but would you check the link please?
I notice that aldi had a couple knocking around the shelves in our local shop. Maybe worth just popping in and having a look
