I've used these on all my phone's including my N20 Ultra
At first they can be a bit daunting to fit but as long as you take your time, watch the tutorial videos and all important use a level surface to work on you'll be good to go.
They are not the cheapest available but widely regarded as the best especially for curbed screens and the fps.
