Dragy 10 Hz Laptimer Accéléromètre, pour mesurer l?accélération (0-100 km/h), prend en charge le GPS

Great piece of kit. Me and my mate wanted to compare our cars but wanted a safe way we could do this. This was perfect as we separately did timed runs in our cars! Relatively easy to do with 2 people as resetting the gps, starting record and then launching the car all at the same time isn’t simple especially if other cars are about. Struggled to find a decent phone holder that was upto the job.

this is a surprisingly handy item and works great , easy to use and can also easily add your own custom range too, seems pretty accurate compared to my speedo in my XKR

This literally makes me want to spend even more money on my car to shave milliseconds off my times. Awesome bit of kit.

Well if you are looking at buying this I guess you know what it is etc, and that there are more expensive rivals. However , as a amateur who uses it every now and then for 0-60 times etc I felt this was the best for me. It has not disappointed, always worked and is small enough to keep discreetly in the car. The app is really good too.

A brilliant device and a must have if you have any interest in performance cars. A little glitchy connecting on occasion, but no biggie for me.

Easy to use, and provides everything you want

Wouldn’t connect to satellite, emailed Dragy and had no response so had to return product, I will now be looking for an alternative.

I bought this to compare times before and after certain modifications and also compare some of my cars against my friends. If all you want to do it show off 0-60 times then it's fine but I find it ridiculous that there is no means of exporting data to any usable format. The only way of viewing your runs is by chart inside the app. To be of any use at all for performance benchmarking it needs the ability to export to csv or similar to runs can be put into a spreadsheet or external analysis tool. It, thankfully, has the ability to set custom gates (40-80 etc) but you can't discount these at all based on time so if you leave the app connected you end up with a list full of random numbers which takes time to sort out and delete the ones which are garbage. Also, when you have more than one car you cannot tell the app "ok now I'm driving this car". It means if you drive a handful of cars you have no idea which run was performed in which car. You can tell the app which cars you drive so why doesn't it assign runs to a car you have listed? Again, this would all be solved by being able to export the data to some meaningful format which is my biggest gripe with the whole thing. I should have paid the money and got a VBox Sport.
