I have one that I can send to you to try. I'll pay for shipping to you and you can use it long enough to determine if it is a good fit for you. If it is, go buy your new one and ship me the old one back (I'll let you pay return shipping). This way, you get to try it before you buy it. For us, it was a godsend... and had it needed to be replaced, we'd have purchased it again in a heartbeat!
If this would help you, let me know. If you don't have enough messages to start a Conversation (Private Messaging) with me, any of our wonderful Moderators can help.
My best...
Jim
