I agree with auto cosmetics, Its hard to see around the tripod, and the legs sometimes pop off the glass, Ive had the same problems, Its hard to get a feeling for this device, If you screw the injecter in too far you can tighten up the break making it hard for the resin to flow into the legs, you can also make it pop off, If its not screwed in enough the injector feels lose... Unlike Autocosmetics I didnt crack any glass, Glasweld told me to hold on to the plunger and let it down slowly, my repairs come out fine... I see guys using really cheap devices and getting good results, so I do agree with someones comments about it being the skill of the repair tech, that seems close to the truth...
