When you open the box and see how high quality the product is and the fact that OEM materials were used (which also push up the price) you will see the value in it. I don't think any improvements can be made to the quality.
Plus you can't put a price on the values it measures, maybe a whole engine replacement in an extreme scenario
I reinstalled my charge pipe the other day, started up the car and noticed straight away the there was a massive boost leak somewhere - according to my P3 gauge. Popped the hood and realised I forgot to reconnect my boost vacuum line! Simple mistake but huge consequences, especially if I didn't pick up on it for a while.
This gauge has saved me from my own foolish mistakes many times, I'm glad I have it.
