The goods were delivered in good condition without defects. Assembly and soldering of unmounted parts was successful. However, two sub-line capacitors on the analog signal board requiring installation were not specified in the assembly instruction. Therefore, at first there was doubt about the need for soldering these capacitors. Finding the necessary power supply 9 V and connecting it to the oscilloscope, primary testing (before soldering all parts) showed the performance of the device. Then after soldering all the necessary components were measured voltage at the control points in accordance with the instruction. Further, having fully assembled the body of the device and connected the calibration signal (as in the photos), the final inspection of the device was carried out.

It's like the description. Almost assembled designer. We need to get some food. The only moment is no power switch. Although in fact it is not needed, K. I put in the food and everything turned on. Put the jumper down. And Xs, what does this have to do with the seller, but I specially chose delivery via 5post to the point of issue, but sent to this scared undermail.

Delivery, since the order, in the Krasnoyarsk Territory took 26 days. The oscilloscope got married and I opened a dispute. The seller contacted me himself, I provided him with a video and he sent another. Of course, I immediately closed the dispute. The oscilloscope came fully assembled. I recommend the seller and the goods.

this little kit is a fun project that should take an hour or so to put together. most of the hard parts, such as smd components are already soldered. there is assembly documents, but they are for a slightly different revision.you can figure it out pretty easily though.

Came as the description, u just need a 9V with central pin connector being positive. Product is very good, helps with viewing wrists PWM, or check wave format in some equipment, is simple but help too!

Before Volgograd, the order came in 13 days. Fully corresponds to the description. Very well packed. In full set. Collected according to the attached instruction. Everything works. Thank you seller.

Note to the seller: the instructions appear to be for a previous version, although it's easy enough to assemble and solder just by looking at the picture of the final boards.

The quality is normal, but the details did not have enough self-tapping and one capacitor, but so everything is fine, and for the trifles did not write to the seller,, only

I liked the oscilloscope, I collected it myself. There were questions but the seller is super, completely competent, quickly answered and helped in everything.

I dont received item.because war in ukraine and delivery service can not send my order.but seller good man. return my money back.thanks to seller.

I saved this designer, it works. Suitable for children for school or for car generator Diagnostics (search for faulty winding or diode bridge).

Highly recommended, I had to put it together and it works very well, it's accurate, the shipment was very fast, I like it very much

Got very fast! Packing foam box. It's whole. I'm picking up. There are no problems with the assembly. Everything is super!

Very nice and quick to ship. I modified it to work with a lithium battery. It seems that a smoothing capacitor is needed.

Good seller! Helps to understand everything. Speaks to the request. Answers immediately. Helps solve the problem!!!!

Super. I collected in the other case along with the generator and counting the kit two in one.

Very well packed. About 15 minutes to assemble ( I'm not a professional), works great.

its received within two weeks. its perfectly working after assembling the components.

Super oscilloscope for such a price! Excellent seller, thank you very much to him!

It came in a foam container, in a semi-disassembled state. I'm gonna drop it.

Normally, I earned immediately ..... not bolts, find such small-problem

Order received, just did not work, found not serviceable chip icl7660.

All good Not tested yet Very good quality product and parts Thank you

Arrived right-hand instruction incomprehensible how to hummingle

Everything has come. Delivery to Russia was fast

Was all correct and working very well

All good

Class.
