Couple of concerns and annoyances.  Spare parts, battery replacements, hoods are not available.  Every time you want to connect to check battery life or make changes to the group, you have to wake the system with the charging cable plugged into a power source.  There is no external wake feature.

Not my experience.  Group indeed needs to be woken up if you weren't using it either from movement or through the shifter buttons afterwhich you can connect your app to make adjustments.  No need to have charge cable attached and plugged into power source.

Welp, I finally got around to installing it but front derailluer's adjustment screw doesn't work screw hole has its threads stripped....  Sigh.  Since I bought it off AliExpress, the options given to me where to ship it back for repair or replacement and they'll only cover $20 for the shipping.  What a pain.  I think I'll just retap it myself with larger pitch threads and grub screw to match.

what kind of hardware comes with the group? ltwoo er9 comes with well over a dozen different bolts for the brakes, as well as 140 & 160 adaptors for both front and rear. In contrast it seems that shimano really skimps on hardware, which i find so incredibly $hitty of them.

Enough to screw the caliper to adapter and adapter to frame  No spares.

Just got mine.  Didn't appreciate the black debris all over the plastic wrap getting on my fingers when unpackaging.  I'm assuming its debris from the foam cutouts or whatever machine did it. 

Anyway, happy to have it now.  Right shifter buttons I'm unsure about. Will see how it feels after being charged up and I can play with it.  Also charging rear derailleur,  not being installed, I needed to place a pencil to keep it open a bit otherwise it pushes the magnetic charge head off the connections.

WheelTop EDS TX alloy version appears to be available on AliExpress at a lower price point:

Thanks.  Pulled the trigger on the Alu with $80 off coupon from AliExpress anniversary sale.  $80 off made it too hard to pass up.  If Carbon was in stock I would have opted for that. 

Ya, maybe my extenders taken it beyond the tolerances it was built for.

How much additional stress is caused to crank arms by using pedal extenders?

ChatGPT
Using pedal extenders can introduce some additional stress to crank arms compared to using standard pedals. This stress is primarily due to the increased leverage created by the extended distance between the pedal and the crank arm. The amount of stress can vary depending on several factors:

Extender Length: The longer the pedal extender, the greater the additional stress on the crank arms.

Rider's Weight and Power: Heavier riders or those who apply significant power while pedaling may put more stress on the crank arms.

Crank Arm Material and Design: The material and design of the crank arms play a significant role in their ability to withstand stress. High-quality, durable materials and designs are better equipped to handle the additional stress.

Proper Installation: Ensuring that the pedal extenders are correctly installed is crucial. Improper installation can exacerbate stress on the crank arms.

It's essential to follow the manufacturer's guidelines when using pedal extenders and to periodically check for wear and stress on both the extenders and the crank arms. If you have concerns about potential damage or wear, it's advisable to consult a professional bike mechanic for an assessment.

That could've caused a major wipeout on the road/trail.
Is this more likely to be a design flaw, or low quality alloy issue?

Need an expert to chime in.
