is there any experience with these?

I have them. The length is adjustable by including or removing an included spacer. There is a damping adjustment and preload is by threaded collar. I'm no racer or suspension expert. All I know is there is a section of bad road nearby that always launched me off the seat with the stock shocks. With the TEC shocks my butt stays on the seat.

do you feel the quality is solid or do they seem cheapish, maybe rusting or coming apart?  Seems I caught some of that impression someplace but I can't remember where.

These are fine. TEC makes a point of telling people that the shocks are sourced from China but are completely disassembled by them and rebuilt to their specs. I see no evidence that they are in any way inferior to the stock shocks and they perform better. I'm still thinking of swapping them for some Hagons but only for cosmetic reasons to give it more of a 60s look.

The price really makes me scratch my head what's the difference to the big dogs in the business like Öhlins or KTech. It's easily a factor of 4-5 price difference.
Do we really pay that much just for the name of this specialists?

Yeah, the range of pricing is shocking. (could not resist the pun, apologies)
I have been searching for the secret doorway to a affordable, performance shock for, literally, years.

I think it becomes more clear when you look at a no-name company that has a product line that covers the field from the cheapy shocks to the very best state of the art in suspension. The price points follow at a almost identical scale.

For example, there is a off-shore company named Racing Bros. They offer everything from the $40 a pair to the $1200 + each rear shocks. Take a look at their website for a pretty darn good explanation of how the top end shocks get the job done. It has good graphics. https://www.racingbros.com/EN/index
    Their product line: https://www.racingbros.com/EN/product You will see that they offer a "Twin Shock" option.

It boils down to how many functions each shock does. If, hypothetically, you had a separate shock for each function you would end up with a row of 5 along each side of the swingarm. And that is way before you get to electronic controllers.   :o Then comes the differences in raw materials and machining tolerances. Yikes, it adds up quickly.
    My demarcation line is separate rebound adjustment. I have no clue where I will end up.

Thanks, quite interesting read. But it also doesn't really explain that huge price difference between these 165 Euro Tec shocks and let's say Öhlins shocks for 950 Euro. Or YSS, it is still factor 3-4.
I am still somewhat puzzled. 150 British pounds. For this the Chinese company making them needs to earn, well, at least something. Then add the transport costs, import tax and the labour cost of Tec reworking them. How on earth can they have better quality than the stock shocks without any side effect. There must a a drawback somewhere. Durability ?

I just re-read my post and you're right. I did a lousy job of answering the question. I guess I was too worried about appearing to bash any particular brand of shock. I'm still not bashing. However, Amazon has pages of rear shocks which look identical to all the others from the outside. Some for $45 a pair, USD. A few for $24. Most in the $75 range, RETAIL.
And if you and I order a pallet of them we can get a discount. Then we can inspect them. Bin the ones that are defective or get a credit for them.
   It is the guts, what is or isn't inside them that drives the price. A non-adjustable, single internal chamber with a single plate with holes in it (valve) is only intended to counteract the spring from bouncing out of control. Add in a second plate on top of the first with a screw and now you can rotate (click) one plate so that the holes no longer line up. That overlap somewhat restricts the oil flow both up and down because the hole openings are effectively smaller. You will see that given various names. Unified, parallel, combined compression dampening adjustment. A new price point.
   It continues on from there with additional internal chambers and bi-pass tubes (some made from stainless) and another set of valves to control the flow in independent directions (up / down) that is what it takes to gain rebound dampening adjustments. All that is fitting inside the same carcass. Now lets add in high speed rebound and high speed compression dampening and bi-pass and adjustment vales for each. Just to say out loud, the high and low speeds are not about the speed you are traveling along the road. They address the difference between rounded mound in the road and the sharp edge of a pothole. That part of the system is even smaller and more precise. Typically that happens at the beginning of the circuit, but not always. Least we forget that every adjustment we can turn needs to resist the pressure from the inside and the dirt from the outside. By the time we reach this part of universe, "sticktion" matters so we get hard coated, extra smoothed main shafts.
Even the rubber in the mounting grommets are a higher spec because, after all, that is the first point of contact between the swingarm and the frame.
    I referenced the Racing Bros website not because I'm advocating for them as a choice but because it is informative even at the opening animation. They also have download user manuals and they make an advanced twin shock product. As you know we increasingly live in a monoshock world. Heck, I even considered (and rejected) the idea of converting my 650 to a single-sided shock.
    So I hope this very generalized explanation of the price discrepancies helps. Looks can be deceiving. And don't get me started on boob implants ;)

I doubt that they can compete with any premium brands and for sure are built on a cheap import platform BUT they do have preload and rebound damping.  They'll also swap springs for my weight

Seems like a deal IF they hold up and are better than stock by a good measure.

I don't have a huge problem with the stock ones, just a little bouncy on bad roads. 

Seems like YSS is the real deal for fully adjustables

The race bros are a bit less $ but I'm just confused at all the offerings.

While, it's a factor, the difference, as with most everything else, doesn't simply relate to cost of production. Ohlins, YSS etc are brands with long-established reputations and come with a particular cachet. Something from China doesn't have that brand power. But it doesn't mean it's lower quality.

It's not dissimilar to paying a big premium for Nike -- even though those are made in China too -- or any other consumer product. We are slaves to fashion and marketing.

I'm not saying the no-name Chinese products are as good. But it should be borne in mind that the quality reputation of the established brands is founded in a time before CNC, when their skill and dedication set them apart. Now, cheaper-produced goods can be as finely engineered, or close. Hence the flood of stuff from China that actually does work. Hence the advent of the RE 650's and their clear break with the company's past in terms of engineering values.
