Pretty disappointed in the Braun Series 9 Pro. Anyone have a better experience?

I bought the Braun series 9 Pro almost a year ago while it was on sale on Amazon for about $239 after seeing that it was a very well reviewed razor. So far it cleans my cheeks and chin super close really happy with that, but it cannot clean my neck to save its life. I usually have to go back with a normal safety razor and clean it up afterwards. I’ve used it in the shower, wet or dry, with or without shaving cream, and it just does not clean my neck or jawline very well. I know a safety razor is the best way to go, but has anybody had experience with getting a fully clean shave with this razor? Pretty disappointed, considering the price that I paid.
