I WOULD HAVE LIKED TO KNOW THE ETA OF ITEMS. BUT EASY TO ORDER. AND THANKS

thanks

quick and easy

Web page needs improvement, descriptions are lacking.

So far all is well. I am very happy. Just a side note, I did just place my order. I haven't actually received the product. This is an update. I am a very happy shopper. The only complaint I have is when I would check on my order to see if it had been shipped, it always said still processing. Next thing I knew it was here. I got my order with in a few days. I am very happy about that. The quality looks great. I installed it with no issues.
