Tenka has a different construction method to the unity due to the potting and it is yet to be seen how this affect reliability over time. it could be worse but equally it could be better. I can imagine that the big caps in particular will be better for the added support and these were known to cause many failures on the unity. But it also has thermal affects that are so far mostly unknown and undocumented.
There is however a known issue with unity switch design failing in some units and and in some specific conditions. If the Tenka uses the same components then its fair to say that this issue will also show up.
The downside to the Tenka is that if any kind of failure occurs then there is absolutely no chance of fixing the broken component. If they follow the same rules as the unity then I expect it to be a case of “if you get a bad one it dies quickly and if it survives past the first month it will last forever”. If that’s the case then the only real question is how much you trust the vendor to honor the warranty.
But as you say there is not enough long term data yet to draw any conclusions about reliability.
That’s great to know. I’m hoping massive stator will stand by their product/warranty if anything does happen. That may be the most important factor throughout the ownership experience.
I moved the Tenka discussion out of this build thread and into its own. Its off topic for a build thread but its also an important conversation. Thanks.
