  • What does SOI mean?

    We have chosen SOI as brand name because SOI is just SOphisticated & Intelligent.

    In German language "SOI" is an acronym, standing for Diligence (SOrgfalt) & Intelligence (Intelligenz).



  • How do I pronounce SOI?

    Easy: just like the girl's name 'Zoe´ (´zo-e' in English).



  • How does SOI actually work?

    SOI is switch-free, hands-free thanks to an adapted sensory technology. Determining factors in SOI´s sensitivity include speed, duration, size and distance of the approaching hand. Behavioural sciences and human motorics played a major role during SOI's development; this was important with regards to hand movements, general dexterity and the time that people needed to find items in their bags. The circuiting was programmed accordingly, meaning that the light turns itself off after an optimal time period. This greatly enhances SOI's efficiency, preventing unnecessary and wasteful prolonged periods of activity. SOI does not react to objects moving in a bag while being carried, or when your hand is too far away or moves erratically. Such movements are 'recognised' as being untypical for a person who is searching for an object. However wearing gloves in winter is very typical for women - but don't worry, SOI even works with gloves on. You will soon notice that SOI lights up the contents of your bag reliably, and timely without the need for you to even consciously think about it.

    The function of SOI is shown in a short video on our homepage, see menu: Multimedia/Videos


  • Technical Data of SOI

    SOI Diameter: 70,2 mm
    SOI Height: 24 mm
    SOI Weight: 48 g
    Dimension of gift box: approx. 110x110x40 mm

    Power Source: 2 batteries type AAA LR-03, each 1.5V
    Voltage: 3V
    4 LEDs, max. power consumption: 40 mA



  • How long do the batteries last?

    SOI is not only very light in weight (less than 50 grams) but also light in energy consumption. High quality LEDs and our own unique electronic circuit programming ensure SOI's high efficiency. This translates into approximately 6000 light-ups (related to one year use this is 16 times a day) before batteries need to be replaced.



  • How do I change the batteries?

    You will find some explanations about replacing batteries here as download:

  • Where shall I dispose used batteries ?

    Following the regulations of Batteriegesetz (BattG), we inform:

    End-users shall not dispose used batteries in normal domestic waste, but are under a statutory duty to return waste batteries. Always dispose of used batteries in accordance with local environmental regulations. End-users may therefore dispose of used batteries at local point of sales or return SOI's used batteries free of charge to us (address see imprint). Please note that in case of sending back used Lithium batteries: insulate + and - poles e.g. with adhesive tape in order to avoid fire hazard.

    Unallowed disposal of waste batteries will harm environment and human health by substances used in batteries. Therefore it is important to observe separate collection and recycling of waste batteries.

    The sign above means that batteries shall not be disposed of with household waste. Pb: Battery contains Lead / Cd: battery contains Cadmium / Hg: battery contains Mercury.

  • Where ist SOI made ?

    SOI is made exclusively in Germany. We work in conjunction with well established companies who are specialists in their respective fields, guaranteeing top quality and due care in production. SOI is assembled manually; this is performed in cooperation with an organisation for disadvantaged young people and the disabled.



  • What do the icons on the SOI gift box mean?

    Icon - 4 in Reihe




    Easy to use  +  affection for detail  +  environmentally friendly = SOI. an illuminating idea





  • Is SOI permitted in in-flight hand luggage?

    Yes, SOI complies fully with rules governing electromagnetic compatibility. SOI passed plenty practice tests accompanying airline passengers and completed numerous round-the-world trips.



  • Is SOI available in different colours?

    At present SOI is available in white only. But who knows what the future will hold?



  • Can a private consumer have SOI personalised?

    From time to time and in limited supply, we offer via our webpage a product personalisation service so that at your request an individual name can be lasered onto your SOI.

    Simply keep abreast of developments via our website or Facebook.
