BroadLink SR4D Door Sensor – Smart Security for Every Entry
Grade A – Mint Condition / Like New (Open Box Only)
Description:
This product is in excellent, like-new condition. It has never been used for regular operation, and any usage — if at all — was strictly for testing or quality inspection purposes. The original box may have been opened, but the product inside is flawless and functions just like a brand-new item
Appearance:
Zero signs of wear. Surfaces are smooth and clean, with no scuffs, scratches, or marks. All components are intact and neatly packed, and the product still has that “new” feel
الدرجة A – حالة ممتازة / كالجديد (صندوق مفتوح فقط)
الوصف:
هذا المنتج في حالة ممتازة وكأنه جديد تمامًا. لم يتم استخدامه في التشغيل العادي إطلاقًا، وإذا تم استخدامه، فكان ذلك فقط لأغراض الفحص أو اختبار الجودة. قد تكون العلبة الأصلية مفتوحة، ولكن المنتج من الداخل سليم تمامًا ويعمل مثل المنتج الجديد بالضبط.
المظهر:
لا توجد أي علامات استخدام نهائيًا. الأسطح نظيفة وناعمة بدون أي خدوش أو آثار. جميع المكونات موجودة وسليمة ومرتبة بعناية، ولا يزال المنتج يعطي الإحساس بأنه جديد تمامًا.

What is "OPEN-BOX" mean ?
An Open-Box product is an item that was previously purchased and returned shortly after. The box was opened, but the product is tested and guaranteed to be fully functional. All open-box items go through two levels of inspection:
- We inspect the product for any visible signs like scratches or marks.
- We test the internal components to make sure everything works perfectly — just like a brand-new item.
Based on these tests, each item is given a grade (e.g. Grade A, B,C or D), so you know exactly what to expect in terms of appearance and performance.
You get trusted quality at a lower price, with complete transparency.
