Harringtons Dog Food - Anyone Used it?

Like a lot of other users on here from posts I remember reading years back, I used to get Skinners dog food from Amazon and it was costing about 25 euro for a 15kg bag. It seems to have gone up in price though and a bag is costing me nearer 30-35 euro now.

I was recently in the North and I've seen shops like Asda and B&M selling a slightly more upmarket brand than I've seen them previously carry called Harringtons...

Has anyone used it?

I know my neighbours moved from James Wellbeloved onto it for their two boxers and are raving about it. I've four Labradors so get through quite a lot of food. I do supplement with raw from my local butcher also.

Generally about 2 15kg bags a month do me. My other option is 70 euro for two bags a month of Gain Elite that a rep has offered.

The ingredients of Skinners are:
Brown rice
Chicken meat meal
Oats
Peas
Whole linseed
Beet pulp
Sunflower oil
Vitamins
Minerals and trace elements
Culinary herb mix
