A blade can look correct while the guide-comb record beside it belongs to a different configuration. That is why a useful sample review starts with the physical items on one bench—not with a broad “professional” label. The aim is modest: identify what is installed and listed for one model, then leave every unconfirmed part of the final kit open.
This scene shows the YH-7108 with a guide comb in a bathroom setting. It provides product context only; the selected sample and project record still determine the configuration being reviewed.
## Put the sample identity at the top of the review sheet
Start the sheet with the exact reference model, sample or revision identifier, project date and the person holding the sample. The public YH-7108 product record identifies an existing professional LED hair-clipper listing for home and barbershop. That title can help a buyer find the record; it does not replace a configuration decision or prove a duty cycle, cutting result, safety outcome or final market claim.
The useful question at this point is simply: “Are we looking at the same selected model that the project record names?” If the code on the sample, artwork and record cannot be matched, stop the review there and log the mismatch. A similar housing or a familiar product category is not a substitute for the exact model line.
## At the bench, make four separate observations
1. Installed blade. Photograph or note the blade as fitted to the selected sample, together with the model or revision reference. The observation identifies what is present. It is not a cutting, durability or safety result.
2. Guide-comb set. The public YH-7108 record lists four combs: 3 mm, 6 mm, 9 mm and 12 mm. Enter those values as catalogue fields for YH-7108, then compare the physical set, markings and requested allocation with the approved sample record. Do not treat the numbers as a promised finished hair length, every intermediate setting or a cross-model fit statement.
3. Other listed items. The record also lists a 1.0 m USB cable, oil bottle and cleaning brush. Its charging stand is described as “for choice.” Give each item its own line. An item shown in a product record, especially one described as optional, is not automatically included in a final retail kit.
