I am always hesitant to buy things at places. I have never shopped, but I thank God that I ran into this store. I want to give a shout out to Manny who with great patience and knowledge helped me get my orders. They are very knowledgeable about their equipment that they sell. They are very compassionate for their customers. I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.
