It's been a whole month since I got this station, I've already used it a several times and I already have a bit of an opinion. I should have more free time with my main job soon, so I'll take some comparison videos and photos later.
Overall my opinion about the TS1M is very good. To be honest, I wouldn't buy it again now because of the high price - I bought this soldering station as soon as it was released and paid 54 Euros for the set with the T245 handle and one tip, including delivery and 21% VAT.
Compared to soldering irons:
C115 with Sequre S20
C210 with L210C, C210 (Alientek C210 clone), Sequre S60P, Miniware TS21, Aixun T208
C245 with Sequre S99 and L245P
What I liked:
*mobility;
*USB-C and DC 5.5x2.5 mm connector. This is very good.
*conservative firmware settings - without additional settings it works from a 65W, 100W, 140W GaN chargers and from a 28V 10A laboratory power supply (I set the C245 power to 200W and I don't change it.)
*conservative firmware settings - does not overheat
*the set temperature corresponds quite accurately to the measured one with all types C115-C210-C245 (note - depends on the quality of the soldering tip)
*power when giving the tip in real working conditions - about the middle, that is, there are worse ones and there are better ones that respond much faster. However, considering that it works with all the sources I have, even if not at the maximum power, I would say that it is very good.
What I didn't like:
*OVERPRICED Now the price is too high, which can only be acceptable to a user who does not need to buy handles, but wants mobility
*Poor quality of handles and unrealistic price. T245 handle with sponge is still usable, but T210 is already too thick for me. Without sponge both handles are slippery, cheap plastic. Analogue ones cost about 5-6 euros.
*No T115 handle. I bought Aixun handle for C115 cartridges with 7-hole connector for Aixun T3B station and it perfectly works with this TS1M station. I like this Aixun handle: soft very pleasant to the touch blue plastic and I use it without sponges. I ordered Aixun handle T210 for Aixun T3B, but this handle is made using different blue plastic - more similar to the one used in other grips - quite slippery without the sponge. Another advantage of Aixun handles - for that price you get handle and 2 sponges. I paid 13,29€ for Aixun T115 and about 12€ for T210 handles (it was discount time, this price including delivery and 21% VAT).
*Non-optimal firmware. T245 handle is recognized automatically, but T115 and T210 ask to choose each time and there is no option to set by default. It's annoying if you only have T245 and T210 handles (or T245 and T115), for example, but you have to choose between T115 and T210 every time
*Not the most optimal sensitivity and power settings, which cannot be changed - even with the original JBC tips, this station does not use full power and it is very noticeable when you use C245 soldering tips and solder a large polygon that dissipates the temperature. In my opinion, the responsiveness to the temperature change of the soldering tip is too low with this firmware
*Does not work with all soldering tips. If the less common C245 with 5.5 Ohm resistance is not relevant, then for example some Chinese C245 tips have about 1.8-1.9 Ohm resistance and do not work either. This is not a big problem, but keep in mind that you will not use just any tips. After long attempts to find gold in the muck when I bought cheap alternative tips, for jobs where I want to guarantee quality, I purchased original JBC soldering tips. Of course, for simple jobs I still use cheap ones, including OSS tips, which cost about 2-3€ with 21% VAT.
Much cheaper handles, but the one I bought requires force to connect to the TS1M, apparently the contacts are too tight.
