Mini review of the steel handle FX9501 for soldering stations on the STM32

Then the chips went well and I gathered all three pens. In this review you will not find recommendations that are better. All individually!
Comparison of the FX9501 steel handle with the 100 MHZ aluminum handle and the KSGER aluminum handle.
Imagine that we are a “Philanthropist, aesthetic,” and decided to get a higher price for a pen to a soldering iron and when you saw the whole assortment came a certain stupor?

Here they go to help us:
Handle overview 100 MHZ.
Overview of the aluminum handle from KSGER.
Overview of the steel handle.
I have the opportunity to compare them all three together.
If we talk about business, everything is clear here, they are all soldered and soldered.
Convenience is a decisive factor, of course, for the majority, the price matters, we will drop the price issue - everyone has their own wallet.
All 3 pens are aligned with the grip of the base, to represent the sting departure.

First point: The steel handle and handle from 100 MHZ have a mercury tilt sensor, unlike the KSGER aluminum handle.
There is no characteristic sound of a ball dangling in a pen.
The response of the station when leaving sleep is more accurate and less phantom wake up.
Second point: I want to highlight the handle grip. The more convenient it is for us to hold the pen, the more pleasant the process of work.
Steel handle

The handle has 100 MHZ (measured at the base, and not on top of the foam, as the foam compresses well and is almost equal to the base)

KSGER aluminum handle

Third point: How it lies in the hand, this is the factor that we lose sight of, but it is he, together with the second paragraph, that affects how convenient it will be to use it in the interval at a time and for as long as possible. If you don’t agree, hold the pen and a thicker marker for longer. On my hand I made a notch with a marker to measure it approximately at the level.

At the handle 100 MHZ

Fourth paragraph (Addition): Many are worried about how the sting is held in the pen, how many pens I had in my hands, not one dangled so that the instrument generally stood out at least somehow on this point from the rest. There is a mini-play on the handles, the strongest sitting position is the handle with a twisting nut with the sting pulled to the handle and it is the same inconvenient for me. The second is the KSGER aluminum handle, the O-ring is located at the very exit to the base. The third and fourth places are the steel handle and 100 MHZ handle. But I repeat, not with one of the pens in terms of the fourth point, I did not feel discomfort at work, from the word in any way. Since this micro backlash is not really noticeable, and there is only if you carefully move the sting with your hands.
Fifth paragraph (Addition): The rotation of the sting around its axis on 360g. inside the handle, I apply medium effort to turn it): Steel handle no rotation, aluminum handle no rotation, handle 100 MHZ there is free rotation regardless of the tip. The steel handle turned out to be the strongest in rotation, but it had an operating time of about 2-3 weeks, like the 100 MHZ handle. Aluminum handle somewhere around the end of September.
I want to notice my hand in the photo, my fingers are thinlong, the hand is not big. It’s convenient for me to use the thinnest pen, at the time of writing the review I had a friend who had a brush larger than mine about two and a half of my brush, he liked the thicker version of the pen.
What exactly is right for you to decide, I hope I helped you with the choice!
For those who do not understand the handle for such a solder station.
