Security & Quality
Checked Camaro & Corvette forums for recommendations. VTT had the majority & it's a USA company so I went with them. Arrived quickly, is very solid & is super easy to install. Based on reviews, expected it might be tighter (harder to get on/off) around the OBD port, but still very secure. Now we can worry less leaving the top down when parked in public.

Great buy for a little peace of mind.
Works well and the installation took 3 minutes. Put the "key" bit holder on your Keychain so you don't lose it!

Great Investment!
I have a 2021 Sierra 2500HD AT4. I’ve been seeing how quickly many vehicles have been getting stolen all from the OBD2 port and a tablet. I mean like in 5 minutes or less your ride is gone. That being said, $100 for this is a tough pill to swallow. However some peace of mind is worth it! I’d rather not deal with insurance on a trashed stolen truck worth 100K and get a check for “current market value” from insurance. This port lock is really well made. Great quality and machined wonderfully. I don’t know about version 1 of this product but version 2 is really made of nice pieces and a truly snug fit. I’d imagine if someone wants to steal something badly enough they’ll find a way. This however should slow them down for sure. They’re not going to be carrying the bits they need to get this off that for sure. If they want to mangle OBD2 in the process, they can have fun. Truly a well thought out product and a nice piece. Beats all the plastic ones I’d been seeing no doubt about that. Well done, VTT!!

Makes it Secure
Was easy to install once I watched the video. It seems to be a good product, I like the red visibility. Seems well made and does the job better than the plastic ones.

It makes it one more step harder for the thief.
A little pricey but gets the job done.

Need a little more improvement Key already rounding off.
Key does not easily align with screw. Notice key teeth rounding. DO NOT OVER TEIGHT. need more than 2 say 3.

Worth the money
I Was in search for an anti theft device for my OBD-2 Port. But i didn’t want no cables to be cut for my obd-2 port. So i found this Product which blocks the OBD-2 port and its pretty Sturdy. GREAT FIT !! No gaps at all in my 2020 Silverado 1500. ONLY WAY THEY CAN TAKE IT OUT IF THEY BRAKE THE WHOLE Port which at that point theres no use . Yes it’s pricey and yes there is some that cost 40$ but this was the fitment that i was looking for. Like i said THIS PRODUCT DOESNT REQUIRED ANY HARD WORK. Took me 5 minutes to install . WORTH THE PRICE !

good quality - a bit fiddly to intall
Very tricky to install, but goes on well and would be difficult to remove without the tool!
