In early 2016 I decided to purchase a Stinger VIP with 1 front antenna to replace my Beltronics STiR-Plus. At the time car BSM systems were becoming more and more common and the custom installed radar detectors available like the Escort 9500ci and it's cousin the Beltronics STiR-Plus just couldn't filter them. If you drove on a busy highway you'd frequently get IO like K-band alerts, desensitizing you to K-band entirely. The Stinger VIP was the first custom installed RD that could begin to filter these BSM systems beyond using timing delays like TSR or lowered sensitivity like Auto on the Escort/Beltronics products. Not only was it able to actually filter out some BSM systems, but you could log radar encounters and send them into Stinger to help them improve their filtering. There were a few forum members who were openly working with Stinger to help develop the product for the US market, and the perception (at least to me) was that we finally had not just a radar detector product that might get a firmware update every couple years, but a platform that would be continually improved upon as the RD landscape evolved. Early testing showed it outperforming the mighty Redline. I had to have one. I thought this might be the last RD I need for many years to come. Once it arrived I did a temporary install with the VIP's patch antenna mounted on my passenger sunvisor and went out for a drive; I couldn't wait to try this thing out. My first Ka-band encounter that night was 33.8GHz while I also had my V1 running along side with custom sweeps, and the VIP DESTROYED it! What a great start! I like doing my own installs, and the VIP is one of the easiest to install requiring only a single cable between the engine bay and the interior cabin. Even if you want to add a rear antenna or laser jammers, you still only need that 1 cable going through the firewall. I wish other manufactures would follow their example. The interface to the VIP uses a touchscreen instead of physical buttons. This has some pluses and minuses. On the one hand it looks amazing and they can continually update the interface as time goes by. Stinger uses these relatively large displays (they have a 3.3" and 5.1" diagonal version) to communicate information with colors; Green means no signals detected, Yellow means a signal is being muted (falselist) either because it's learned that signal is a stationary false via GPS or is a BSM system, or Red which means it's alerting to the signal. If you have a rear antenna it will also provide directional information. There's also a cool spectrum analyzer display option that shows the frequencies being detected, but in practice it's tough to read while driving. The downside to the touchscreen is that trying to operate the VIP while driving is difficult because you can't feel what you're doing, you can only glance over and take a stab with your finger and hope it hits where you intended, as you're otherwise focused on driving. A lot of modern car radios have this problem now too. I now know my preference is to have physical buttons for controls. This interface is where things began to go down hill with me and the VIP. The original VD-10 display that it came with wasn't readable in direct sunlight and was later replaced by the VD-20. The VD-20 is VERY bright in direct sunlight, but it's not visible head on while wearing polarized sunglasses. If you can't see the screen, you can't adjust it's settings or see which frequency is being detected. With that said, the first week I had the product the auto-brightness feature didn't work properly. For me there was no happy medium brightness that I could use, I need the display at full brightness at day and very low brightness at night, otherwise I either can't read the screen or the interior of my car is lit up and blinding. I reported this issue to Stinger and they never came back with a solution. That was 2 years ago and I'm still having issues where the auto-brightness will stop working for weeks and then just start working again on it's own. When this last happened a couple weeks ago, I reported it to Stinger HQ and learned it was a known bug they still haven't addressed... after 2 years. The audio alerts are problematic too. X and Ka are a distinct sound, but K-band and laser are comparatively quiet. With the volume down so that X/Ka are reasonable you run the risk of missing a K/laser alert. Keep it high enough for K/laser and your ears will be bleeding every time you encounter Ka. On to the core of the product though, radar detection. The Stinger VIP uses the term "FalseList" when it mutes learned stationary radar signals (GPS lockouts) and when it's filtering BSM's. While others have reported problems with the GPS lockouts, these have worked well for me. The lockout radius aren't too big and I haven't had any situations where these stationary falses weren't learned, but I do occasionally see them alert due to weather related frequency drift, which I had also experienced with my Beltronics STiR-Plus. BSM filtering is good, but like many top tier RD's it will alert to BSM systems that it can't filter from many car lengths away. Sometimes the VIP will filter tougher BSM's like Acura/Honda, but then allow punch-throughs unlike other RD's that will either filter or not filter a signal. I've also experienced a 10 mile trip behind an Acura MDX that had my V1 alerting the entire time but the VIP completely filtered. Police radar detection on the other hand is unreliable. About 50% of the time I encounter police K-band the Stinger VIP will either alternate between alerting and treating the signal like a BSM and filter it, or filter it entirely. I've had this happen many, many times in areas that have no stationary falses, so it's not a GPS related issue. I've been sending Stinger HQ logs and video of these encounters for 2 years now, and it's still an issue. I've had to run 2 RD's because I can't trust the Stinger VIP to actually alert me to police K-band. As an enthusiast I've been OK with running 2 RD's, but I don't think this product is safe when run alone if K-band is a threat where you drive. Then there's Ka-band. The VIP is HOT on Ka, besting a Uniden R3 that I recently purchased both on and off-axis. But there's always a downside to the Stinger VIP, and in this case Ka-band is also auto-learned for GPS lockouts. So if you have regular speed traps that you encounter with a Ka radar source, the Stinger VIP will learn and mute them. There's no way to limit which bands are auto-learned, it's an all or nothing proposition. You can't turn off auto-learning either, only FalseList entirely with no option for manual only lockouts. I only just learned of this "feature" after 22 months of ownership while reporting it to Stinger as a bug and having them reply that auto-locking Ka-band is by design. 2 years ago I purchased the Stinger VIP knowing it was still in development, but unfortunately it remains in the same state today with little improvements. I've sent logs and video to Stinger HQ in the Netherlands (where their engineers are located) regarding all of these issues (and more) as they happened, but as of v4.0.52UK and this date (2/14/2018) they all remain unaddressed. I don't know if Stinger is unwilling or just unable to fix these problems, but at this point I find I still can't trust the product to reliably alert me to radar, it's primary purpose. Making the situation even more frustrating is that the hardware is capable of being HOT but unreliable due to buggy software that COULD be fixed but so far has not. ------------------------------------- Good * Radar antenna is HOT and has beat everything else I've owned, including the Uniden R3 * Display's use of colors * Single cable between engine bay and interior cabin makes install of RD/Laser easy Bad * Police K band is often filtered like BSM's * Police Ka band is learned and locked out * 2 years and the VIP is still in a broken state of product development Ugly * Display is hard to read with polarized glasses * Audio alerts are quiet for K/Laser * Poor ramp-up * Touching the display often results in a double press, muting and unmuting the alert * Auto-brightness randomly stops working * Only a single radar frequency is displayed at a time unless you use the impractical spectrum analyzer mode * GPS and BSM filtering both display as "FalseList" with no differentiation TL;DR - The Stinger VIP was promising but Stinger has failed to make a reliable radar detector after more than 2 years of development. Maybe someday they'll finish it, but for now I would avoid it.
