Most usefull thing. If you print adapter and make taps. It will heat up quite a lot. I was able to use whole battery in 20min. It is usually enough for 50-60 times M3x10 taps (into PLA). It is quite strong and if not enough, you can just help it. Charging fast, i would advice you to buy few spare batteries. It is not really battery friendly so you may will need to replace inner bat with new after some time of using it. I was not able to change settings, The file inside is corrupt and will not regenerate. They tried to help me but ware ultimately unable to solve the problem. (It is very useful even without it). Thx All promissed parts came fine in like 1.5 weeks to middle europe. (did not expected it to come so fast) (sry for my english)
The ES120 works great. Chonky. I wish the carrying case and cable had the same premium feel, but they work great too. Case can fit 6 bits, the straps are a bit too tight and hard to put the items in. The bits are also uncomfortably close to the ES in the case, if you are worried of scratching it.
