Choose ordinary PLA, then Grey
The reference selection is ELEGOO PLA (RFID), Grey, supplied on a 1 kg spool. It is not PLA+, PLA Pro or a refill. The UK reference code is GWUK-EL-3DF-PLR0814; use the material and pack description as well as the code when checking another regional shop.
Do you need the RFID feature?
Check which hardware the tag is intended for. Do not assume that the presence of RFID means automatic recognition in a Bambu AMS. For a third-party reel, manual material selection and a checked slot assignment may still be part of the setup.
That is a convenience question, separate from whether the material prints cleanly. It should not earn a performance advantage merely because the spool has a tag.
Compare the whole purchase
Look at the delivered cost for one reel, what the pack contains and the return or support arrangements available in your country. Promotional bundles make sense only if you need the quantity and colours supplied.
The label and local product page also need to agree on material and diameter. A similar photograph on a different regional shop is not enough to prove that two listings describe the same version.
For print-quality decisions
Use measurements and photographs from the exact material, not an RFID specification or a rating for a different ELEGOO range. This page is a product guide; no hands-on rating is assigned here.
