Caig Labs CW100P Circuit Writer Pen, Silver-Based, Silver

Work fine

Batalle muchisimo para poder sacar el liquido, literalmente tuve que casi doblarlo completamente

Was a little difficult to use on my project but after a little brain storming I figured out the best way to make it work. I had to squeeze some of the product out on a piece of paper and dip the pen in rather then squeezing the pen as I drew it made it easier to get a straight line. The product worked great. I used it to repair a maytag dishwasher ribbon would much rather spend a few dollars on this product then to purchase a whole new face unit for $150.00 worked well to fix my dishwasher.

La tinta no es de muy buena calidad, las veces que la intente usar no me funciono para nada y muy rara vez funcionaba. No sirve

I've used this product in the past, it always worked very well for membrane key matrix modifications.The pen I ordered here in Sept 2020 results in 24hr cured traces with very high resistance, which varies, some lines have no conductivity at all. Caig is a good company, and says this one Caig product is fery shelf life dependent. Caig does NOT have a production or use by date on the pens. If they did this QC issue could be avoided. They said they would send me a replacement, but I wanted to post a warning. All my modified membranes are now junk.I didn't use or test this pen until just 4 days past 1 month so Amazon's great return policy didn't apply.I will only buy these directly from Caig in the future.
