A pen is good when it works. Often this is not the case. I want to point out some design flaws and give advice on how to use it to anyone who bought it. The metal or plastic case is so thin that it can easily break under normal use. He is very thin. The top quarter of the pen, right where it is glued to the battery case screw, has the case cracked with normal use.2. The top quarter of the pen is held to the battery screw *only* by glue and friction. This glue weakened for me and decomposed, eventually becoming unusable. I had to glue the top quarter of the handle to .3. The spring in the battery compartment is too short. Take a good pair of pliers and stretch them 25 or 50 percent to make contact with the top of the handle. Someone on youtube suggested taking apart a ballpoint pen, taking out the nib, cutting a 1/4 inch section off the end and sticking it in the compartment. Apparently this has worked for many people.4. Debris can collect on the threads of the battery compartment screw that connects the top half of the pin to the bottom half. This dirt can prevent a good connection. Take a damp paper towel or something similar and wipe off the black dirt to ensure charge flow.
