How about his oversized sprockets - has anyone used them? Feedback?

That is somewhat true, especially, if you are able to modify drive sprockets to fit. What it does not take into effect is the tensile strength of the chain 'chassis'.
In other words Oregon, STIHL, etc., expect 3/8 low profile chain to be run on saws up to a specified power and bar length, and size the components (tie straps, rivets, etc.) accordingly. Higher power saws, and longer loop lengths, put additional stress on these components, increasing the risk of failure. Chains intended for larger, higher power saws, have heavier duty components.
If it's on eBay, you can file a report/complaint.
