I went to 3 stores looking for the battery I needed. I didn't find the battery or a sales person who cared to help. Then I stopped here. The man working was very attentive and helpful. I had a sensor with a low battery on my house alarm and it was causing the alarm to make noise day and night. The employee immediately handed me what I needed. He took several other customer service steps like greeting everyone who walked in professionally and he know the product. I won't go anywhere else for battery needs now.
