UPDATE: Company is super-responsive and cares about their products and customers. I wrote an email describing in detail the issues - and they wrote back within hours and had done a bunch of research to find out they have a new part with a cut-out that will fix the problem of the ribbon cable getting worn. They even sent a picture of the new part and comms with the engineers. Very impressed with BillConch. It's been a few weeks - safe working great - love it! Hello! My name is Aaron, I own and operate a computer repair and service business for the past 13 years in Richmond, VA. As an electronics technician, electronics hobbyist designer, computer systems engineer and union electrician of 20 years - I would like to offer some constructive criticism to the company, a simple repair/fix on their assembly line, and a fix for current and future owners that may see the following behavior of the BILLCONCH Model:B1 Gun Safe. While it was disappointing to have an issue, I really like the safe, the features, the build quality, etc. I would have given it 5-stars on ngclab.com if not for my “issue”. Since I was able to diagnose and repair the problem, I’m still keeping it – so, let that be a testament to this product! Thanks! After repair, everything seems to work great, including rejecting fingerprints - which seems to be a complaint - where it "accepts any fingerprint". I did not find this to be true and FP appears to accept/reject fine. I propose that perhaps this issue is also causing issues for others and their unit's ability to recognize/reject their prints. PROBLEM: 1. Unit does not turn on or respond/charge with battery or USB cable. 2. Unit turns off while pressing on fingerprint reader or on plastic bezel with very little, to moderate pressure (Specifically to the right, or right lower side of the FR). In my specific case, on arrival(!) - the unit worked fine during setup, inserted codes and fingerprints and charged the battery (which came practically fully charged!). I later (same day) observed the unit turn off instantly while enrolling a second user. The unit did not turn back on without somewhat forcefully tapping on the bezel, between the fingerprint reader and the speaker grill. I was then able to repeat the “instant off” condition by applying slight pressure on the bezel, while “lifting” the bezel from the frame ever-so-slightly caused the unit to power back on. Sometimes the unit would “stay-off” while other times it would turn on and off based on if the bezel had downward pressure applied or not. DIAGNOSIS and OBSERVATIONS: 1. A SCREW that affixes the PCB to the rear of the bezel may cause a direct-short condition. The screw is one of two screws, located beneath the flat-flex ribbon cable responsible for connecting the GND, 3.3V and LED ring-light power to the Fingerprint reader’s daughter-board. In my case, the small, Phillips-Head screw had “sharp points” that had pierced the flat-flex ribbon cable, direct-shorting the 3.3v and GND lines – causing the unit to turn off. A. The back cover/bottom of the control panel ever-so-slightly bulges at the location of the screw/ribbon cable, indicating there is no extra room between the black “backing panel” and the cable/screw. When the front panel is screwed down flat, the flat-flex ribbon cable is being pressed into the PCB mounting screw, causing rubbing and ultimately, an electrical short. Providing extra room here would solve the issue, but may be unacceptable, as it would increase the overall height of the control panel and require substantial retooling and manufacturing of a new part. B. The screw responsible for the damage has a slightly taller head than the other mounting screws, maybe by a half a millimeter. Using a flatter, thinner screw head would also fix this issue. C. The screw pierced the flat-flex ribbon cable due to what looks like the “witness marks” of the driver that put it in… that is, the screw’s cross-pattern deformed slightly while being torqued down, causing metal spikes at the four inner-corners of the cross-pattern. A better machined screw head or a higher hardness screw would fix this, likely. SUGGESTED CHANGE FOR COMPANY/ASSY LINE: 1. Apply a small piece of Kapton tape over the screws, below the ribbon cable. FIX FOR USERS: 1. Remove the 4 rubber grommets and screws located on the front panel. 2. Remove the back cover by snapping the back cover away from the tabs and expose the rear circuit boards and electronics of the front control panel. 3. Unlock the flat-flex ribbon cable from the far-side labeled GND-3.3V-LED by moving the black plastic clip horizontally, away from the connector by a millimeter or two. 4. Remove the flat-flex cable from the connector and flip the cable up and back, inspect for damage and identify if your screw has pierced your cable. If so, I removed the screw and used a small metal file to file the screw head flat, eliminating the tiny ridges/spikes that were causing the damage and making the screw less-tall. Then, apply a piece of Kapton tape or perhaps electrical tape over the screws, located below the cable. Reassemble and good luck!
