I am satisfied with the overall construction of the wand, 3d printed end caps are super durable, the LEDs are recessed into each end cap, which is nice, no worries of damage during a hard core contact flow sesh. The upgraded led knob leash is worth the small upgrade fee. The only part of this wand that I did not agree with was the string that is provided.....it snapped the first time I used it. I use kevlar kite string or thick nylon cord depending on if I'm long stringing or short string wanding. But I give it a 10.
