PROS
Outperforms many other batteries like Panasonics A, B (3100, 3400mAh) when the discharge rate is high (3-5A), it holds voltage higher than any other 18650 up to the end of discharge, especially at the second half of discharge curve. Steel bottom on protection board.
CONS
Slightly on the longer end of protected 18650 due to the button top as well as protection board with a steel bottom. Fits into ML-102 charger with a little push. I guess quite standard among protected 18650s. They are more like 18700s.

Looks decent despite it's price. Switch works well and is on a 20mm board. Comparable to Convoy lights, same boot too, same pill except slight variations in size.
CONS
Reflector is difficult to fit on 16mm board if not impossible, on a 20mm you may be lucky to get it down enough and not short anything, it's a hit or miss and you will have to adjust things. Only 2 o-rings, had to add another 2 since it does have enough grooves for 2 on each side and the thread does not cut them. Threads could be better but they work.
Good host, used it with 1574903 lens (holder has to be slightly modified to fit and seal against front o-ring). Stock reflector should work fine but it is wide on the bottom and it will definitely make contact with cables on a 16mm board. On 20mm board it may work on some close enough. Use thing wires and insulate. Used a 20mm SinkPAD but that means modifying the pill. Would be nice if they did not add the silly ring on the pills so one can fit 20mm boards right away. Makes a nice floody light (with 1574903) that is seen from all angles well and even though it's 60° it does provide enough hotspot and light to the front, good for walking, indoor, but I made it for a bike so when it bounces it should flicker minimally compared to throwy lights while being seen from all angles to the front easily.

Well sealed - foil glued and air sealed, closed by screw on lid that is secured by a another seal Even though it is only 30g, I've found that I don't really need to use much of it to solder things. Health and storage warnings on the package.
Works well for reflowing LED emitters at home and other stuff where solder paste comes in handy. Did not notice any difference in melting temperature compared to normal solder wire.

Brittle Can't handle the weight of a P&S compact camera 247 g (0.54 lb / 8.71 oz) Rubber does not grip and is slippery Weak joints Cheap screw Not compatible with Joby at all, joints are bigger but weaker Head has no secure ring, only a button
Totally disappointed. Thought it would last at least a year instead it only lasted a couple weeks. Rubber is slippery, does not grip. Joints are bigger than on a Joby but weaker and wear out quickly. Head has no secure ring for the button. Screw is smaller. Joints are brittle and after a couple weeks of using it the camera fell down from the tripod with the head joint attached to it. At least the camera did not suffer any fatal damage. Can't use it anymore. The head joint plastic has a tiny crack in it and that means it is very weak and obviously to a point where it falls all down if upside down. Joby is overrated at 320g, it's usable for 250g but not for long, maybe a year or two depending on frequency of usage. With this clone tripod, couple weeks tops. :( Anybody planning to use this, probably only with a tiny P&S camera of weight around 100g and do not fiddle with the joints much to not wear them out. The plastic is brittle anyway so it will break sooner or later. Can't imagine anybody using this in the winter, freezing temperatures. Worthless to buy unless you have other plans or use for it than a camera tripod.
