IGPSport SR Mini Radar Tail Light

[havox07]

Noticed this on AliExpress, has anyone tried it? Am curious how it compares to the Magene L508 as the price is comparable. Haven’t found much discussion online.

They've supposedly completely changed their detection algorithm since that video so it might be outdated? I hope Petr can give us an updated review soon. I don't hate my L508 but the battery life is poor, and since IME IGPSport puts magene to shame when it comes to GPS unit battery life I'm hoping the same remains true for their radars

These devices are only effective if you really trust them. If you don't trust them you will ignore them and then they are useless. They MUST be reliable and consistent in order to be trusted.

Saving $40 isn't worth questionable performance in a safety system. Buy a garmin. If the $40 matters that much, buy a used Varia. Be happy.

As much as I would love to I refuse to buy any device with micro-usb in 2025.

Then get the new wahoo radar? From what I've seen, it's the only other radar next to Varia that actually works (aka constantly and reliable).

Didn't know that. Was expecting they use the same. But even if that doesn't mean it's now magically good. I wouldn't buy one until someone with a good review reputation has put it through some tests.

Bought one on the Eurobike booth 1,5 weeks ago - Had it on yesterday first time.

Completely leaves the Magene L508 dead in the water!

• Much much more brighter light modes
• more range  - on a straight road the detection starts about 150m (also the car icon on the Wahoo starts on the bottom, with Magene, never)
• NO false positives on my home turf (Magene always had a couple ones, especially at 1-2 same points EVERY TIME)
  
• better battery, better light modes
• looks good IMO, good mount under seat rail, so more sturdy and higher view point.
• Retail $99, got in on Eurobike for EUR80.

No experience with other brands, though. Only used Magene L508 because I got a good RMB discount for it in China.

I prepare a (German) video, but still waiting on an email reply from those guys in regards of disabling the blinking... Hard to use on German roads, as the "Smart" radar will currently always blink when a car approaches, as well as when you brake it will happily disco along - Would rather disable those "features" as it maybe not street legal here.

Looking forward to the video. I wouldn't mind upgrading from the L508

Any feedback on standby battery use would be great too - that's another bugbear of mine with the L508.

There are two specific behaviors of the Varia that I wish would improve. I understand the technical limitations behind them, but they still need improvement. These are what I am always curious about with competing products.

1) The ability to filter out objects that aren't actually approaching me. For example, riding on a road that parallels a highway. Steady stream of objects getting closer, but not approaching me, results in a useless stream of alerts.
2) When an object approaches from behind (car) but maintains it's distance (same speed as me) I receive an alert when it first approaches, but if we go around corners and visibility is interrupted, the radar stops seeing it because its position hasn't changed in relation to mine. The car vanishes from the radar even though it is still there. This happens a lot on windy mountain roads when cars will be polite and wait for a safe spot to overtake/pass.

Whichever product can solve one or both of these issues will be a winner.

My Magene radar light has been flawless other than the battery life

I agree - my experience with the Magene is great other than the battery life.

My Magene radar light has been flawless other than the battery life

I had the Magene for 2 years as my primary back light. So in general I would also say it worked fine, recognized most cars. BUT I have like 1-2 "Ghosts" per hour or more. There is spots, where it always "recognizes" cars, but there is nothing there! Did you not have those kind of issues?
Battery... yeah, I would guess like 5hish or so.

IGPSport blew it out of the water for me, still waiting for a reply from those guys on how to change blinking, or timeline for software updates.
I want to to a side-by-side comparison on the same road, maybe this weekend. Same spot, then I can compare the distance between the 2.

Otherwise: SR-Mini is lighter (49g vs. 63g for L508), smaller, brighter, has longer battery, looks better etc. at the (!)same retail price of about $99, so for me it's quite clear winner.

Fun fact: At Eurobike, I asked the iGPSport guys how many R&D people they have, he said about 100.
Same question to the Magene representative: 38 (Not sure, if that same dvision is also responsible for their vast hardware portfolio from exar wheels, to smart trainers, powermeters, groupset, lights,... nowadays).

No issues with false positives, but occasionally false negatives (i.e. it won't detect a car that is there). Most likely when there are multiple cars in succession it might miss later cars.

[kbernstein]

I get quite the amount of false negatives personally on the L508, but thankfully always vehicles I would have otherwise heard. Only 1 in 10 motorcycles are detected I would say. False positives happen too but they don't worry me much.
I seriously doubt IGPSport has 100 r&d employees, unless they mean unpaid beta testers like you and me. But either way I have had excellent support from them from my GPS unlike magene, and would trust them more when buying a future product
