When I searched Tannus Armour on this web site I found info scattered usually under specific bike brands and some other experiences have been different than mine. Maybe a specific thread would be helpful for those considering them and I'm curious regarding experience others have had.
I bought them for a BH/Emotion Rebel Gravel X with 700 x 17c rims and Schwalbe G one tires that don't have puncture protection. I ride in very hilly areas where downhill coasting can regularly get you to high 30's mph to over 40mph even with some braking. At that speed a sudden flat seems like it could be disastrous. The liners add some limited run flat ability also.
Local bike shop had them listed on their web page but they didn't have them in stock and didn't offer to order them so I got them on Amazon. Cost $85 for a pair including tubes.
Issues I had with the order were that the liners for the size I needed have a size range for rims imprinted on them that wasn't listed either on the Tannus web site nor the Amazon listing. Minimum rim size for 700 x 35-40c is 19c but my rims are 17c. I messaged Tannus, it took a couple days but they responded that they would fit 17c rims - then why list 19c as a minimum on the liner? (I didn't bother asking that but it crossed my mind). So I went to install them and found the enclosed tubes were 18-23c whereas a chart on the Amazon listing stated a required 23-28c (the Tannus web site stated 20-28c if you check that chart) along with a statement to be sure to order correct tube size. I sent another question to Tannus about this but wanted to go riding so I got correct size tubes from the local bike shop - then got a message from Tannus that 18-23 tubes would work fine. They were sending the smaller tubes because of difficulty sourcing tubes, it seems they could have sent this info with the product, but whatever.
I followed their installation video instructions including use of baby powder and they installed very easily as they said they would. I had been somewhat concerned that others have reported difficulty with installation and even that bike shops had difficulty with them. Maybe it depends on tire size but those reports are difficult to reconcile with the ease that mine installed.
So far I have ridden them about 40 miles on pavement as well as some gravel. They do seem to add rolling resistance which isn't trivial to me especially pedaling without power assist. That disadvantage is offset to me with peace of mind having puncture protection as well as run flat ability. They also seem to take some of the jarring out of railroad tracks and sharp breaks in pavement. I have been deflating my tires after rides to help reduce compression of the inserts over time, that isn't a bother to me.
