Presidium Replacement Probe Pen PS2-2 for Presidium Gem Tester II (PGT II) and Duo Tester II (PDT II)

Great item, fast shipping. Thank you.

Bought this a few months ago and it is still going strong. I was a bit worried it would be finicky being that it is a replacement pen but it worked perfectly.

I had this probe pen for only a week and was very careful with it because the original pen that came with the presidium lasted about 2 months and the machine arrow malfunctioned , finding out from another user it could be the pen I bought another, which fixed the problem but this time the needle on the pen went into the probe and stayed there. I had only used it a handful of times was very upset . I am replacing it for the third and last time. but when the pen goes bad it can affect the machines function also so it is best to replace your pen probe before you replace the presidium. They need to make the safety cap so it stays on the pen it is rather useless . All I did was gently use my pen a few times and the needle disappeared into the pen. I will give up and go to another brand if this pen breaks. I am 73 and dont understand how to return the item so I will take the loss

This works like it is supposed to. We are pleased with this purchase.

I guess they changed the design

Useless as tits on a bull

It's working better than my several months of usage pen was working. I was aware that I also needed to recalibrate the new pen/probe to my device. Now it's working great!.

This product stopped working after 2 months of use. For price I expected It to work longer. Tried to get it replaced through Presidium and they have not responded.
