Where each product wins
In a head-to-head where the two options are identical, there is no winner. The comparison table above shows matching prices and specifications across both listings, so neither can claim an edge. If you are choosing strictly between these two, they are effectively the same product; the only useful comparison is against other interceptors.
Commercial Grease Interceptor Grease Trap Stainless Under Sink Grease Trap US
This listing gives you a grease interceptor with four-stage filtration, which is a solid fit for separating mineral, animal, vegetable, and mixed oils from water. The automatic shut-off is a thoughtful touch: it lets you place the unit outdoors, and it will shut down automatically when rain hits, reducing the risk of overflow. For a kitchen that needs a dedicated oil-water separator under the sink, this unit's filtration design is the main reason to consider it. The trade-off is that the same rain-triggered shut-off will pause operation during wet weather, so if you need uninterrupted service in an uncovered outdoor spot, that behavior could get in the way.

The second listing matches the first in every confirmed detail. The overall dimensions of 35 x 25 x 23 cm (13.8 x 9.8 x 9 inches) give it a compact footprint that suits an under-sink installation, and the stainless body is built for long-term use. Easy installation and convenient use are part of the design, which can make the setup less of a hassle. There is no separate advantage here in price or specs; the value is in knowing that the product you receive should match the advertised dimensions and materials. Between the two listings, either one works the same, so you can pick based on which listing you are more comfortable ordering.
Final choice by use case
For a kitchen that needs a compact under-sink grease interceptor, this unit at USD 49.03 is a straightforward pick. Because the two listings are identical, the choice between them comes down to preference rather than product differences. If you need a larger capacity, the fixed 18-20L capacity is the main number to compare against other options; the 4.8 cm wastewater inlet is also a fixed spec to keep in mind.
