Bests & Worsts Reviews from Amazon

Wow...I'm disappointed. I really needed this thing to work. I was very impressed with the video. I read some reviews on here regarding fluid leakage from the pen, and I thought it can happen, but maybe their quality-control will step up. I received this unit and it was partially covered with the liquid material that leaked out - not a lot. But it isn't the type of stuff you want on your skin, and there's no way around it unless you open the package with a cloth or paper towel handy. Also, the pen body is much more flexible than I would have thought. It's like a stiff black plastic drinking straw with threads that don't seal that well. Okay, not a big deal. But the LED wouldn't light. There are two ways of activating it - sliding a switch down that presses one of the LED leads to make contact with the battery, or by squeezing the soft battery case to do the same thing. Nothing. I don't know if the LED is defective or the battery was dead. I suspect the latter. I had an application for which this item would have been perfect. But I can't use it and have to send it back. Very disappointed. ***************************************************** ********************* UPDATE ************************** ******************************************************* I began my return process with Amazon, but in the meantime, the seller noticed my review and promptly sent a replacement, unsolicited by me. The replacement arrived today and the LED light was fully functional. I didn't notice any leakage around the pen, but I might still expect some, given the material it's made from. The item works as advertised, though I will say that the resulting cured product is a bit more flexible than it appears in the video. It isn't glue, but if you've had any experience with actual metal welding, you will have more success - you need to make a good solid mechanical connection for good strength. I updated my review from one to four stars - for the product itself. It isn't the cat's pajamas as it appeared, but it's pretty good. The seller is outstanding - and I very much appreciate their efforts to satisfy this customer.
