    Exactly what I needed

    Extremely fast shipping, works exactly as described. Just what I needed to power a water pump. Also comes with 15 different adapters, so im sure this will come in handy in the future for a multitude of different projects. Straightforward design, and Extremely easy to understand. Also has brackets on the side for mounting it to a permanent location

    Great for most things

    It works as intended, for those devices that dont get used as often and you inevitably lose the power adpater. Or if the original breaks.

    Essential Household Equipment

    Every household should have one of these, because nobody manages over time to keep track of all the various wall warts and charging cables for all our electronic devices. There is scant chance you won't find the right plug for your device in this kit. The knob is a little touchy and requires attention to set the proper value, but it soon becomes easy as you observe its somewhat laggy behavior before holding steady on a value.

    Good value, manageable quirks.

    I use this to power a eurorack synthesizer that has a particular voltage (13v). It works well, all the different attachments as well as it having higher potential amps than most similar units makes it a good value. My only peeves are that voltage control knob is sensitive, It will be easy to accidentally bump it to a different voltage if not careful. I have also noticed the voltage will slowly drop down a few tenths when being used for 1 hour+.

    Very versatile

    Worked great as a replacement power supply for a Department 56 Christmas village lighting system. The variety of adapters made it easy to pick the right one I needed. Saved me from having to buy a new lighting system.

    ​Great price and highly versatile!

    This kit includes a huge variety of plugs for almost any device. It’s perfect for hobbyists, though I do wish there was a way to lock the voltage setting to avoid unintended changes.

    Varible voltage power supply

    Power supply is very useful for my Lionel train set which uses about 10-18 Volts.The only disadvantage is the Voltage always drops by almost 1 Volt after about30 minutes of use.
