TL/DR: Expensive, stand is not perfect, and it adds some weight, but I've tried three different case solutions and watched tons of videos. This is the best, most overall protective case you can currently buy for the TriFold. Get it.

My Berfy case arrived today when I got home from work and I quickly put it on and have been using it for a few hours now, so I thought I'd share my impressions. After dropping my TriFold on the front screen over the past weekend and shattering the front screen protector on the cheap ass plastic front case I was using (the phone itself was not damaged so score one for sturdy design, Samsung) I've been going caseless on the front while I waited for this Berfy to ship, and I can't tell you what a relief it is to finally have some solid protection again.

CONS

Price: Even with the recent price drop, it is still way too expensive. 127 USD (down from 147 a couple weeks ago) is just too much for a case that's not offering military grade protection like Otterbox or something.

Left Hinge Cover: The front screen protector has a little flap that covers the smaller left hinge for drop protection, which is inherently good, but when unfolding the phone, that little flap scrapes or slides against the hinge causing an uncomfortable feel almost like over time it could scratch or damage the hinge.

Weight: The case adds a little thickness and weight to an already heavy device. You have to decide if that trade-off is worth it to you in order to have the best shock and drop protection currently available for this 3 thousand dollar phone.

Stand: Unfolded in portrait, the integrated kickstand is not at all acceptable. The device stands at a 90 degree angle and a slight breeze would blow it right over on its front screen to potential disaster. You can see in the attached photos I have a magsafe adjustable kickstand attached to the back which works perfectly for portrait mode. Unfortunately if you plan to use the phone in portrait mode propped up with just the Berfy kickstand you can forget it completely.

PROS

Stand: Unfolded in landscape, however, the integrated Berfy kickstand works better than any other kickstand solution I've seen or tried. It is solid, steady, and sturdy, with no chance of falling forward or back. Perfect for media consumption which I use the TriFold for more than anything else.

No wobble: With every other case I've had on the back, and for the few times I've had the phone caseless, the protruding camera bump makes the the phone wobble terribly when placed on a flat surface on the back. This problem is almost completely ameliorated by this case. Practically zero wobble when put on its back side. Massive improvement.

Magsafe: The back case has integrated magnets for compatibility with all magsafe devices. A little weird that the magnet doesn't feel quite as strong as the magsafe sticker that came with the Aulumu kickstand I'm using, but if you are into magsafe accessories, Berfy has you covered.

Solid feel and protection: For obvious reasons I am not going to field test this case for drop protection and shock absorption, but I've had this TriFold for more than a month and a half and I haven't felt more safe and secure the whole time since getting this case. Front screen protection, double hinge protection, top and bottom edges protected, camera protected, all the boxes are checked here. It's like a weight has been lifted, honestly, to be able to have this in the pocket of my pants next to my keys and not worrying about scratches and scrapes, not to mention dropping out of my jacket pocket and taking nasty fall on the concrete sidewalk. Also the surfaces and sides of the case have a nice smooth premium feel to them. I really like the way it feels in my hands with the case on.

I think if you still have the funds after shelling out over 3k for this phone, in the vast ocean of inferior, cheap, practically worthless case solutions for this device, you'd be very smart to pay more for this case which I feel is the best money can buy.
