can anyone tell me the pros and cons of the dexcom g7 gcm?

sorry for any mistakes, english is not my first language.

i'm thinking about changing my cgm to the dexcom g7 because i'm having huge troubles with the libre 3 (pressure lows, allergic reactions, lots of connection errors). can someone with experience with the g7 tell me things i need to know about it? does it also have these pressure lows? any advice is welcome!
