  • Most likely better on anything else than garments

    Pros:

    Delivers what you'd expect for this price :)

    Cons:

    The double-sided tape looks like something that will not probably stick to textile too well. Not that I actually tested this on a garment, as my use for this product was something completely different.
    The visual pattern is hard-wired so you really can't call this product a equalizer nor a VU meter at all. The hard-wired sections are simply lit according to the volume picked up by the microphone.

    OtherThoughts:

    Cable connecting the battery pack and the transfer is not slotted, so it can be connected either way around. This does not damage either part, but simply, the direction to which the visualizer graphics are activated gets reversed.
    On a 3VDC supply, the current draw is slightly under 180mA with the visualizer completely lit. Thus, don't expect to get many hours of use from a set of batteries.
    I also tested running the product on a +5VDC supply and with this, the current draw went up to around 300mA. With this voltage, you'll get more brighter light from the visualizer. Not sure how the increased voltage and current draw might affect in the long run. This also increased the high-pitched sound emanating from the internal transformer.

    Bottomline:

    I can't really see this product permanently sticking to a garment or able to withstand machine wash with the double-sided tape included. If you're planning to do so, using some sort of a textile glue might prove more long-lasting.
    The product is definitely a lot better if attached to any other surface more solid (f.ex. plastic or wood).
