The staff is knowledgeable. However, buyers beware of their return policy. Read the fine print on the back of the receipt before walking out of the store because they won't disclose them to you. This is even more important when they open up the packaging for any tool before you buy it. If you find that you don't need the tool after all, good luck! You won't get a refund even if it was unused and they were the ones who opened it!
