Product worked very easily with all the hard work done by the manufacturers themselves. Awesome product

The sensor arrives quickly, I needed a little help to make it works correctly as I didn't not have the correct program or driver installed. I contacted the seller and he answers me quickly and send me the correct program and driver and after that it was perfect. I have two devices, one help me to park my camper at ground level, and the second is for my school as i'm a science teacher. I recommendend the product and seller.

I bought this for measuring angles: specifically for setting up woodworking machinery. The advertised 0.2 degree accuracy would not have been sufficient, but the precision of 0.01 degrees gave me enough hope to risk buying one, and I was not disappointed.Certainly the initial "out-of-the-box" accuracy is not high - I am not sure if it was even within 0.2 degrees. However, you can zero the angle reference to the current plane, and for the next few minutes (maybe a bit longer) you get 0.01 degree accuracy before the readings start to drift. You can test this easily by mounting the WT901BLECL on a straight edge, zeroing, and then inserting a piece of paper under one end of the straight edge. The WT901BLECL is both accurate and repeatable (+/- 0.01 degrees) short-term.My main criticism would have to be the plastic shell, which does not even have a very flat surface on its bottom, let alone perpendicular sides! The first thing you need to do is to mount it on something flat.Battery life is excellent - one charge kept it running for a full day of measurements.Compared to self-contained angle measuring devices (ones with inbuilt displays) it is very nice to be able to have the display somewhere easy to read while the sensor is in some awkward position.Machinist's levels can do better than 0.001 degrees, but at 0.01 degrees I am starting to see variations in the flatness of my "machined flat" cast iron table, so for me the benefit of higher precision would be minimal.Being battery-powered, small and light means I can mount it next to the spindle motor on my CNC router and check how the angles vary as the spindle moves around (x, y and z).Note: I would not trust this to measure a 90-degree angle; instead, keep the WT901BLECL horizontal and mount it on an accurate square if you need to measure a vertical. The WT901BLECL can be used to compare two vertical surfaces within 0.01 degrees, or to compare two horizontal surfaces within 0.01 degrees, but going between a horizontal surface and a vertical surface even short-term probably gives you closer to the specified 0.2 degree accuracy.Overall I am very happy with this purchase.

I struggle with how to rate this as the hardware itself seems really good. And it is easy to install the drivers and test with their own software. But for my use case it does not work as there are no generic Windows drivers. So, things like Windows Store apps, Unity, .NET Xamarin/MAUI, and generic programing frameworks will not detect the device.They have their own libraries and examples for custom development which seem easy enough. But I was just trying to get sensors on my PC to help aid in cross platform development (like a Surface Pro has built in for example) and not be tightly coupled to this specific device.Their support is great too as I emailed to ask, and they quickly confirmed there was no generic Windows driver. They also promptly offered a refund.So, depending on your use case this may or may not be the device for you. It does work with Windows, just not in a generic fashion.

This is a small and light device. The documentation provided with the device and available on-line is excellent.I am in dispute with the manufacturer of a new car that I recently leased. There is obvious vibration which I wanted to measure. This device was perfect for obtaining saw-tooth plots in 3 main axes, and demonstrating that the car has a significant vibration problem (which the manufacturer had refused to accept).The Bluetooth allows the signals to be transmitted to a smart-phone (Android or i-phone) app. This was perfect as I was able to attach the device to the steering wheel (and other parts of the car), which would not have been possible without the wireless connection (wired to keep the battery charged also works). The i-phone GUI also worked well with Start and Stop buttons for recording when I was driving on a smooth road surface. The graphs were displayed in real-time (and also recorded on the phone for later analysis). The app has an aircraft style attitude and heading display. The on-off switch allowed easy control when the device was needed.
