The same product, described twice

This listing and another on this shelf carry the same five bullets under different seller names. The eyepiece range, the phone range, the rotating holder and the assembly description all match. One figure does not.

Thirty-two rings, or three

This listing says thirty-two additional rubber rings; its twin says three. For an accessory of this price, thirty-two is implausible and three is ordinary. Both are reported exactly as published, and the discrepancy is the point.

The two ranges that matter

Twenty-eight to forty-nine millimetres of eyepiece body; sixty-five to a hundred and five millimetres of phone width. Those two figures decide compatibility entirely, and both are given.

What is not there

Dimensions and weight. Its twin publishes both — 150 × 85 × 40 mm and 88 g — which is the one respect in which the two listings genuinely differ.

Availability

German, French and Spanish Amazon stores ran from 9 € to 12 € on the day of the survey.

British Amazon store lists it in local currency, which the euro range above sets aside.

Italian Amazon store stood above 1.6× the cheapest country. A gap that size normally means stock forwarded from abroad rather than a seller on the ground, so that figure is left out of the range above.

American Amazon store gave no result whatever, so the buy button there opens a search rather than an empty page.

Figures as Keepa reported them on the day this page was last updated. Stock and pricing shift without warning.
