What are your thoughts on the Mileage Booster on DL flights?

I have an upcoming trip that has 4 segments which means for a little more than $200 I can essentially buy 12,000 bonus miles. Now I know these don't count as MQM's but if I throw this into this trip (which my company is paying for) I pay $200 for a total of 17,000 miles, 5,000 of which are MQM's.

What do you think, worth it or no? Trying to grab as many miles as I can to fly my GF and I to South America next year. Already have 125K miles banked, so an extra 17K certainly doesn't hurt.
