I concur with the Encore Pump.
https://youtu.be/xYpHty0p1CwI have been using the Encore for several years. It's easy and you get the complete kit. Priced right too. The only drawback.....You should only be "Pumped Up" for 30 minutes......That is only the down fall. You know how that is....Once you get started, who's in a 30 minute rush? That sucks.....
I interchange between Trimix and the Pump. My Uro recommends using the Trimix no more than about twice a week, three max. Plus, Trimix is not always my best option. Something about sticking a needle in your "Tool" is not normal. I must still be a chicken. So for me, it's easier to "Pump up" than stabbing your Tool. The Pump.....It's over when it's over.....with the Trimix...you might end up with a visit to the ER.
Plus, if you do it right.....I let my better half have the pumping fun, then she can see it grow. I will NEVER let her stab me.
So YES.....The Encore is the way to go. Good luck.
