Excellent equipment, I’m already testing it and it gives very good readings! The after-sales service is excellent, they sent me the video to see how it works, etc!!! The shipment took longer than usual but it’s an issue with CNMEX logistics that leaves much to be desired… with imile and jyt and faster
A***t (verified owner) –
Fast and careful shipping… mini touch OTDR… menus in French possible… the only defect might be but still… it’s the wavelength of test only in 1550… but it will do the job and we’ll see if the tests with active fiber give correct results…

The product has been received. It is correct and complete. Fast delivery and works well.
L***n (verified owner) –
The device works well, it has several functions (laser, photometer, signal simulator, reflectometer, event map) I recommend it!

Thank you, seller. A good mini ODR 📡.
AliExpress Shopper (verified owner) –
Very good, I recommend it. Tested and approved using precise measurements, it makes work much easier.
M***s (verified owner) –
Very accurate for under £100. Got this for basic fault finding and surprisingly works very well compared to the 5k ones
AliExpress Shopper (verified owner) –
I’ve used this to test an approximately 600m run of os2 singlemode fibre. For the small business user or technician it’s absolutely excellent value for money compared to the ‘named’ alternatives available. Accuracy was very impressive and it picked up all splices on the length of the cable and identified a break in a core very quickly. Stable light source is also very useful if you have something to plug into on the other end. For the price this is absolutely excellent, don’t let anyone tell you otherwise.
