To be honest I don't know anyone that looks at handling times.

For that one needs to select the postage section unless it's mentioned in your description. Even then it doesn't always show in postage.

You can still post immediately.

And if it eleviates the defect issue it's worth it IMO. Won't think eBay will fix that in a hurry.

Just looked at some of your listings and handling time is not shown anywhere.
