Review on Efficient Mini Micro Jewelry Repairing Torch: Your Solution for Perfect Jewelry Restoration by Sirious Cavalli

This is a replica Smith mini flashlight, so it is not of the highest specification. Another review found the threads were wrong but in fact the threads are correct but very tight due to lack of specification and quality control. I've added some dry lube to the threads and they work fine and don't leak. It gets the job done, and while I have an old Smith that had rotted hoses after 20 years of drying, it's of much better quality.
