I purchased a totally wrong product and my husband pointed it out...several times. I learned that this type of product cannot usually be returned because a seal is broken. I sent the item back to the company with the hope it could be given to someone who could use it. I was very surprised when the Company contacted me that they would return my purchase price less a very reasonable re-stocking fee! Customer service like this is very rare. I rate this as a 5-star company.
