'Symply' dog food...?

Anyone feed their dog 'Symply' dog food available from Pets Corner? If so what size is the kibble, does it look like good quality food and does your dog do well on it? Every time I go to Pets Corner to buy dog food, they always try and sell it to me. I buy breed specific Royal Canin from Pets Corner and they tell me I would be better off buying Symply as it doesn't have all the additives that Royal Canin has.
