I use quite few before for my Samsung Note 9. From my experience its quite good for curved screen rather than tempered glass due to easily the tg lifted up at the edge but not sure if using high quality tempered glass mybe could avoid that. Touch sensitivity is good and s-pen also can be use normally except got some mark on the hydrogel if you press so hard with spen or nail and can be seen if the screen is off. Other than that its good rather than naked to avoid micro scratch

Yes but worth to wait till 15 April for SE2/Ip9 that probably will launch on that date. Mybe pricing for ip8 will reduce or ip9 itself worth getting as A13 on it.
