Review on Samsung Galaxy S21 Ultra Silicone Case with S-Pen Bundle - Black (US Version): Enhanced Protection and Ultimate Convenience by Danielle Smith

Overpriced for what you get, nice to hold. Need protrusions to keep it from slipping out of hands. But as with most cases like this, there's no port cover for port C. The only benefit in this case, I think, is that it holds the S Pen, which doesn't add much in terms of protection. I would look elsewhere unless you need an S grip that fits your case. There are many options, but not many of them support the S Pen.
