The E61 Gecko pen light is a VERY-VERY SOLID BUILD with the same HEAVY DUTY CLIP as the E62 but it is MUCH-MUCH MORE VERSATILE then the E-62 and is also WAY-WAY MORE VERSATILE then the TP10 Tactical Pen Light Because it has 4(FOUR) INTERCHANGEABLE TIPS/BITS(INK PEN, GLASS-BREAKER, INKLESS PEN/SCRIBE, STYLUS) VERSES ONLY ONE(1) Ultra Hard STEEL TIP for BREAKING GLASS or Self Defense that the TP10 and the E62 HAVE ONBOARD THERE MODELS!
ONLY THE E61 GECKO Model has the MAGNET ON THE SIDE GIVING YOU HANDS-FREE LIGHT by ATTACHING IT TO ANY STEEL OBJECT(CAR HOOD/DOOR/SIDE PANEL,BICYCLE/STEEL FRAME, REFRIGERATOR etc..etc..) and ONLY the E61 Gecko MODEL gives you a 270 degree FOLDING/EXTENDING LED LIGHT ARM to MOVE IN AN ARC THAT WORKS IN CONJUNCTION/TANDEM WITH THE MAGNET ON THE SIDE TO LIGHT UP ANY WORK AREA IN THE FIELD TO GIVE YOU ULTIMATE FLEX-ABILITY OF LIGHTING!!
As it STANDS the only ADVANTAGE the E-62 has OVER the E61 Gecko Model is the ABILITY to have a CUTTING KNIFE/RAZOR-BLADE.The E-61 GECKO has the 270 DEGREE FOLDING LED LIGHTS ALONG WITH THE MAGNET on the side making the USE of the LED LIGHTS MUCH MORE VERSATILE!Along with the 4(FOUR) DIFFERENT INTERCHANGEABLE BITS PEN, STYLUS,INKLESS-PEN, GLASS-BREAKER MAKES THE E61 GECKO MODEL SUPERIOR/BETTER and a MUCH-MUCH MORE USEFUL TOOL/GADGET IN THE FIELD!
As for the TP10 it does NOT have the VERSATILITY & FLEX-ABILITY OF LIGHTING the E-61 Gecko can PROVIDE and has NO STYLUS or INKLESS PEN/SCRIBE MODE OF OPERATION and from what i have heard about the TP10(I have one in shipment right now) it has a FLAW with the LACK OF THREADS, it is hard to get the cap on tight and it loosens easily i will be checking this out my self first(1st) hand shortly when mine arrives
So for the ABOVE REASONS i would have to SAY and CONCLUDE THAT THE E-61 GECKO MODEL ABSOLUTELY REIGNS SUPREME and SUPERLATIVE in the Wuben Tactical Pen Light UNIVERSAL ARENA/ZONE!!
In REGARDS to both the E61/62 MODELS I PERSONALLY CARRY BOTH MODELS-E61/62(And will soon also carry the TP10) to have ALL MY BASES COVERED but if given the CHOICE to have to ONLY CARRY ONE(1) IT WOULD BE THE E61 GECKO HANDS-DOWN!I HOPE this may HELP GIVE SOME INSIGHT INTO THESE Three(3) INCREDIBLE PEN LIGHT MODELS FROM WUBEN!BEST WISHES CONAN;-):+}}
