  1. Awesome 5 Star Review

    Good product

  2. Terrible and unusable 1 Star Review

    Posted by on Apr 21st 2019

    This item was a waste of time and money. I understand why it was on clearance when I bought it, because I didn't even get it to do a reading once. I attempted to screw an RDA into it, and the connection to the unit itself came right out of the base, like it had completely corroded. I had to use pliers to remove it from my RDA.
    Absolutely a case of "you get what you pay for" except considering the brand, I expected better.

    It turns on, but it wont read anything I put on it. That's a bummer, but for $0.99 ill use it as a built deck I guess.

  6. BROKE ON FIRST TRY 1 Star Review

    Posted by on Dec 26th 2018

    I screwed my tank into this thing and the whole socket came out. I had to get pliers just to get it off my tank. Then I tried screwing the thing back into place and it does not work, the socket is just held into place with some glue and now its not making contact. Peace of junk. I paid almost five dollars to have it shipped. Disappointed.

  7. Coil Master Ohm/Volt meter 5 Star Review

    Posted by on Sep 20th 2018

    When I saw this on here for $0.99 I seriously didn't believe it. I ordered expecting it to be a piece of junk that didn't work or have some kind of issue... but it actually works great! I'm shocked... There as absolutely no other place where you will find a deal like this... Even at it's original price of $7.49 it was still a good deal. At this price you would be a fool not to grab one. Unbelievable value!
