    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    1. very similar spots of all lasers
    2. good quality
    3. power supply of 3V (however lasers have survived also 5V power supply)
    4. have a groove for an easy fixation in a tube or something like that

    Cons:

    1. Elongated laser spots
    2. Cables are about 50mm long

    OtherThoughts:

    1. Typical laser spot size at the distance of 150mm it is about 2-3mm x 4-6mm
    2. short cables, so i needed to solder them for extension

    Bottomline:

    In general leave a good impression at the acceptable quality/price ratio. Where quickly delivered.
