Medical device reps and pharmaceutical reps which one has the money way?

I am a pharmaceutical representative, I used to do devices, in general both are almost the same, because the two customers are the same, (except otc), devices have consumables, equipment, to do this line there is no such thing as starting fast, on the two words, adhere to the first period of time is very bitter, the late income is very high, so if you can get into some well-known enterprises, it should be relatively easy to a lot, but the well-known enterprises will not generally look for a newcomer, so it's a contradiction, it is recommended that you take a backdoor, into a large enterprise, mixed for two years, it will be easy later, if not, start from scratch, at the beginning to be prepared to get no money.
