Things I liked:The adapter works perfectly, no need for teflon tape with the delrin seal. Things I would have changed:Shipping method and charges. Item arrived in a box large enough to hold several HUNDRED adapters. I was charged $7.99 for shipping and the actual postage marked on the box was $5.99. It could have been shipped in a padded envelope for about $2. I will shop around before I buy another small item from Pyramyd.
