DSE 901 v 501

Back in the day when I used regular atty's I would use the 510 for a better throat hit and the 901 when I wanted more flavor.

 

Remember, any review is based on the person doing the review. Some users swear by the 901's, where others think that the 501's hit best. You will need to be the judge for yourself. Heck, that's half the fun right there. Same thing regarding devices and fluids. Everything is viewed quite differently.
By the way, I like both 901 and 501's for what they do.
Good luck.

 

If you want to compare the two you need to make that both attys have the same ohm rating. Lower or higher ohm ratings can make more of a difference that the type of atty.
