They replaced the coupler on my blender for $10 when other shops quoted me $35+ (I provided the part). The technician did it right there on the spot in just a few minutes. He also stayed open a few minutes passed their normal hours because I called and said I was very close but delayed by traffic. I think that is about as good as customer service gets. I will come back if I need an appliance serviced again.
Note to the owner - this shop is excellent but extremely difficult to find unless you already know about it. It does not come up at all when you google "small appliance repair" or "kitchen aid repair" - but a bunch of shops that don't service small appliances or kitchen aids do. I think investing in search engine optimization (SEO) and maybe yelp advertising would make it much easier for customers to find you!
