When a gasket fails, the first question isn't which seal is cheapest-it's which gasket actually fits the machine in front of you. That's the choice in the seals, gaskets, and o-rings aisle: one part is a set of blender gasket rings for a NutriBullet cup, and the other is a small-engine gasket set for specific Honda models. They may both be gaskets, but they're meant for completely different jobs.
Quick verdict
If a NutriBullet blender cup is leaking, the 3PCS Gasket Seal Rings are the no-fuss pick: they're sold for that blender setup and come as a set. If your repair is on a specific Honda small engine, the Rotary Brand Replacement Gasket Set 12314 is the one matched to a known Honda fit. Match the gasket to the equipment before you compare prices.

Where each product wins
The blender gasket rings win on cost and spares. They sit at the lower end of the price range and come as a set, so a second worn seal doesn't mean another order.
The Rotary gasket set wins on fit certainty. It's tied to concrete Honda part numbers, so if your engine is in that family, you're buying a part designed for that job rather than a broad compatibility ring.
Product notes
3PCS Gasket Seal Rings for NutriBullet 600W and 900W Blenders

If you're repairing a NutriBullet 600W or 900W blender, this set is the low-cost place to start. At $5.99, it includes three gray gasket rings for the 3-cup blender cup, so you have a spare after the first replacement. The rings are food-grade silicone rubber, BPA-free, and non-toxic, with a durable, flexible, easy-to-clean design. They're meant for the blade assembly area and should work with many 600W/900W personal blenders, not just a single model. The trade-off: the fit list is broad, so you need to confirm the size and style of your cup before ordering. If your blender uses a different seal design, this particular set won't help.
Rotary Brand Replacement Gasket Set 12314

This is a different kind of gasket purchase. The Rotary Brand Replacement Gasket Set 12314 is priced at $37.10 and made for Honda engine part numbers 06111-ZE7-406 and 061A1-ZE7-801, covering GXV160 and GCV160 models. If you're working on one of those small engines, this set gives you the specific gasket configuration the job calls for, from Rotary Corp. The limitation is fit: it isn't a universal set. If your engine isn't in that Honda range, you'll end up with a costly part that doesn't match your machine. Because it costs about $31 more than the blender ring set, you want to be certain of your engine model before buying.
Final choice by use case
Choose the 3PCS Gasket Seal Rings when the leaking part is on a NutriBullet blender cup and you want a ready-to-use replacement set. Choose the Rotary Brand Replacement Gasket Set 12314 when your repair matches the specific Honda engine fit it's made for. Let the machine decide, then spend accordingly.
