Does anybody know if the plastic installation tool is a standard size? It slipped a couple times and the plastic has been deformed. Where can I find a replacement?

I  received the powermeter but it's not compatible with CUES FC-U6030-2. The big chainring is 110BCD but the small is not.
I ordered two cheap chainrings (BUCKLOS 50/34) which seems compatible. A photo review already shows it installed with the PP5.
The seller forgot to ship it with the 4 bolts and I had to order them separately and wait more. I ordered bolts for double chainring.

I noticed that when I install the bolts with the powermeter, the bolts extend about ~1mm. It doesn's become flat with the big chainring. Is this gonna be ok? Should I get bigger bolts for triple chainring and cut them to make them compatible with the double chainring + power meter?

I think it's compatible, cause it's a 24mm spindle linke the p515 https://it.aliexpress.com/item/1005005506880823.html

I was wondering about the axle length and if it's too long for the 86mm bottom bracket.

Is it compatible with CUES 50/34 (FC-U6030-2)? Can it be paired with iGPSPORT BSC200?

Hello, it's my first post here. I'm thinking to get a road bike and TT-X40 seems like a really good value. I also found the R5 pro which seems to be the same bike with different branding. They claim that it can be shipped in EU without the need to pay any taxes.
Has anyone any experience? Is there any justified reason to avoid that?
I would also like to source the parts and build one myself but I cannot compete with that price even with low tier pars. Furthermore the more expensive parts (150€+) will be subject to import taxes.
Is the TT-X40/R5 pro my best option on that price range (~700€)?
