Should You Switch from Luyianxi 2PCS?

Yes — they appear to be the same product. Both listings share ASIN B0FD48FQR8, same product images, same description, same carbon fiber spec, same price ($44.99). The difference is purely the storefront name: Luyianxi is a 216-review listing and PLUSINNO is a 2,052-review listing for the same physical item. When you order from either, Amazon ships the same product from the same warehouse.

If you haven't bought yet, ordering through the PLUSINNO listing gets you the same product with 2,052 buyer reviews (vs 216 on Luyianxi). The 9× more review data means you can read hundreds more bug reports, durability stories, and use cases before buying. If you already own Luyianxi, keep it — you already have the validated product, just listed under a different storefront name.

Carbon fiber is lighter and more sensitive (better bite detection), but more brittle under hard impacts — a car-door slam can snap a carbon rod that fiberglass would shrug off. Fiberglass is heavier and more durable under abuse but transmits less bite detail. For hiking/travel where weight matters, carbon fiber (Luyianxi/PLUSINNO) wins. For rough use with kids or rental situations, fiberglass is safer.

Depends on your use case. 2-piece combos (like Luyianxi) give you a backup rod if one breaks, or a second rod for a partner or child. Single rod kits are lighter for solo travel and cost less per rod. For solo backpackers fishing alone, a single rod is enough. For couples or family trips, 2-piece is more practical. Both Luyianxi and PLUSINNO are well-reviewed at this price tier.

Both listings claim freshwater use primarily. In practice, occasional brackish water (estuaries, beach fishing) is fine if you rinse the reel and guides with fresh water afterward. For dedicated saltwater multiple times a month, the exposed hardware and basic drag will corrode within 1–2 years. For dedicated saltwater, spend the same money on a purpose-built Penn or Shimano combo with sealed drag.
