I bought a couple blades there and ask for some advice to put them on. The salesman said it is easy just squeeze here and read the instructions. I tried to figure it out and I couldn't. I took the blades back and told another salesman I couldn't figure it out I would have to go somewhere they would help me. He said no problem and refunded my money. He never offered to help me. I feel like they don't want business very bad to treat someone that way. If it is the policy of that store not to help a customer then I won't be one there.
