JMHO
I fell in love with the graphics...already had numerous HV
devices. (Higher volt)..I WANTED it because of the look.....now, I own a big Chuck and I NEED it. Why? you might ask......
1. The Chuck at 3.7 Volts hits like or better than ALL of my other 5 Volt
mods
2. The Chuck works EVERY time...ALL the time.....ON time....no cleaning sticky switches, no fussing with sandpaper on the connection, no hooking to a USB passthrough, no muss, no fuss....(wise to give a cleaning for sanitary reasons and good upkeep like changing oil in car, it still runs but will run longer with proper preventive maintenance)
3. The Chuck at 6 Volts will throw you to the ground....when
batteries are fresh mine has read at 7.2 volts (according to my master electrician friend who brought a meter to my house and checked it out...I know nothing about amps,volts or other electricalisms)...that is the power behind a Chuck...compare a hyundai motor to a porche.....you can go faster, right? Well, you can get more vapor with a Chuck.
4. The Chuck is a bit heavier...due to being made of copper and not "airplane alum" or stainless or other configs...this has been touted as a negative, for me it is a positive. I feel the sturdiness of the Chuck prevents me from damaging it while it is in the "black hole" (my purse as my husband calls it), banging shopping carts, whacking gear shift of car or dropping off bed when I fall asleep with "Sir Charles" in hand.. All have happened and the Chuck just keeps on Chucking.
5. Now you WANT a Chuck.....after you get the Chuck, you will find you NEED a Chuck.

6. Jeff, the master God of Mods, has superior service and puts his full attention to every detail of your Chuck and is kind, warm and very funny and he interacts with we Chuckleheads and "knows" us for who we are and our personalities and therefore can produce a Chuck with our requests in conjunction with his vision of what we like and want.
That is my view and I am sticking to it (and not sticking to the other switches..LOL)
Hope this helps....Join the family...you are welcomed with open Chucks to the Chuckternity ward at the Saturday thread...where all expectant Chuckers wait and whine for their new babies...
