what has your experience been with refurbished 6P?

I've bought refurbished electronics in the past with no problems, but wondering what kind of reputation Huawei has with their refurbished models.

Where I live it is not uncommon for people to be selling "new refurbished" 6P's, most people explaining these were replacement phones.

I wonder if people have lost confidence in their phones after having to have them replaced and decide to then sell them?

For those of you that have refurbished models, what has your experience been?

Any thoughts on Huawei's reputation as far as refurbishing?

Thanks for any advice!
