Next decoding challenge request from New Zealand.

Hello today 14 June 2019 I have finally received my lock back from Priyer. Meantime there is no contact with him so I do not know what is going on with him now. I hope he is ok and will publish his review soon.

Now, I like to welcome new participant Swynndla from New Zealand. He is very good in opening combination locks presented on his channel here:

Now I will prepare new combination set up and will send my Polish Combination Lock to Swynndla on Monday. I hope he will enjoy decoding my mechanism and he will make nice video from the try as well with final review.

Next worldwide decoding challenge will start soon. Lets stay in touch.

Priyer’s final review. Update 10.06.2019

Due to his illness, Priyer could not perform the Polish Combination Lock evaluation video earlier and present his results. Now he is healthy and promised to publish the review video in coming days. I wish him all the best and a lot of health.

UPDATE as of 10 June 2019. Nothing , no contact from Priyer. What is going on? No idea. We can only wait until he will respond somehow.

UPDATE as of 03 June 2019. Still nothing, no contact with Priyer, very strange I hope he will make the final review and send my lock back.

UPDATE as of 25 May 2019. I do not know what is going on with Priyer now, no contact. I have sent many e-mails with request for information why he didn’t made the final review of my Polish Combination Lock yet and how he is feeling now. I have no idea, no info back what is going on and why he didn’t reply. Still waiting for his final review and my lock to be send back to me. Without my lock I cannot continue this challenge so I hope Priyer is ok and will send it back to me soon.

If you have any contact with him please ask him what is going on. Thank you.

We are waiting for Priyer’s final review.

Hello , we are still waiting for the final review Priyer should do. I hope he can do it soon (we certainly waiting now too long) and I will be able then to announce next participant.

I hope Priyer can send back my lock ASAP after final video will be made.

New Worldwide Challenge request from Priyer just arrived.

Hello due to the fact that there was no more requests from people who have more than 5000 subscribers I decided to cancel this requirement. Now anyone who has YouTube channel about lockpicking can participate in my Worldwide decoding challenge, new rules are updated now.

There is new request from Priyer to decode Polish Combination Lock. Here is his channel:

He picked already such a “unpickable” locks like: the Bowley lock, the Forever lock, and the Yuema 750 to name a few.

So lets the challenge begin soon. You can find more info on proper page….

I wish Priyer all the best and good luck in decoding. The Polish Combination Lock is now going to Canada.
