Stocks that buffer against S&P 500 losses and cap gain a good play at this time?

Hi,

I recently learned about S&P 500 Buffer ETFs from Innovator ETFs. I was mostly interested in PDEC and UDEC. It looks like they have an expense ratio of around 0.79% and cap gains at around 13% for pDEC and buffer S&P500 losses up to 15% and anything beyond that, you would lose money on assuming you hold from December to December annually. UDEC is even crazier and buffers loss from -5% to 35% in the S&P500 with cap around 12% . These are relatively new and wanted to see if anyone had any experience in these ETFs?

Thanks!
