Aliexpress mcpcb, kdlight, difference between price and quality?

Flashlight Modding and DIY Parts

So I need some mcpcb for some xhp70 and xhp50 emitters. I looked on aliexpress and found 10pcs of copper mcpcbs for only 5€. Would they be any good ? They are copper dtp but don't know. Lht flashlightstore (kaidomain) of aliexpress sell kdlight copper dtp boards, which seem good quality, nice and thick too, but the price is like 5€ for only one board. Or I can buy the leds on kdlight boards mounted directly. Are the cheaper ones any good? I've had some similar boards for the xhp50 and 70 and they seem fine, what is your guys opinion? Are more expensive boards better with cooling etc? eas of soldering?

Noctigon boards are best.
Some KD boards (incl 5050 and 7070 footprint boards) are similar, but have different upper layers with lower acceptable temperature (dont overheat them when soldering).
Sinkpad pcb are also good enough.
Not so many chinese boards are dtp, but all depends from yiur project. Sometimes dtp is not necessary.

yeah I hear the noctigon and sinkpad are the best, but hard to find. The chinese ones are copper dtp too though. What do you think as far as cooling and quality goes of the chinese ones?

To make any other suggests we need more information:
-project type
-led current
-links to the boards you are looking

Link to those Mcpcb with DTP that are 10pcs for only 5 euro.
I don’t think they don’t have DTP.

I have messaged some sellers on AliExpress that claims their Mcpcb have DTP but haven’t gotten any response back (no response usually means that they don’t even know what they have written in the item specs or it’s just a lie)

Sometimes they respond to what they think is right (or what the manufacturer have said to them) but is still wrong. (One example is that I tried to convince a seller that what they sold is not what they write in the item specs, after a week of messages and alot of proof I suddenly stopped receiving response back but they changed all their item specs)

I don’t believe those boards are DTP.
Not sure how it’s with XHP types of leds but I had same “issue” with DTP boards for XPG/XPL/XML leds, Noctigon are the best but they are expensive so I had a look at aliexpress (because KD mcpcb-s are not that much cheaper than Noctigons) asked some sellers, most did not respond, bought some that were cheap, they ended up not to be DTP, kinda expected, anyhow, I came to conclusion that the best solution is to buy already soldered led on dtp board from Intl. not cheap but cheaper than buying led + mcpcb and then soldering them.

The KDlikter/Kaidomain boards are also DTP. Or else my 219C on 6 amps would have already been fried.
