The package to Ukraine in the city of Kyiv, the city of Kharkiv, was received in 12-14 days, very quickly arrived, thank you, thank you to the store for a good product at an affordable price. Thank you of course to AliExpress for the services provided. I recommend to all other buyers not to be economical because sitting around saving money doesn’t buy anything. Human life is short, very short human life, and then when you finally decide to buy something, it may not be necessary or it will be too late. So buy without hesitation, very good product, good price, good quality. Thank you to the store and thank you to AliExpress. I haven’t checked it yet, but the external packaging seems undamaged, everything is well sealed, and it seems like a complete set. I recommend to all buyers not to hesitate, good product, good quality, fast delivery.

Delivery 13 days. Works well with a 68Ah car battery. At a setting of 23, it burns the 0.1mm strip that comes with the kit; at 16 it welds normally.

Haven’t tried it yet but looks good

Worthwhile for the price. Shortly after detecting the contact, a short circuit is activated. In stage 1, the length is approximately 4 milliseconds, per level approx. 1ms more. (100 levels). The circuit contains 5x HYG011N04 MOSFETs, each carrying approx. 220 Ampere.
Only the ladder rails are somewhat weak, even though they are reinforced with brass rods.

Excellent product, it can be welded to the BMS battery.
In principle, I recommend it, the only thing needed is additional protection with acrylic glass for the board.

Excellent product arrived on time and in good condition, so recommended for those who want to try it. Without fear of success.

It works. Purchased without cables. Beginners should purchase with cables. Preparing cables avoid mechanical connections with poor quality. When possible solder connections with tin. Avoid too long cables. Connection to electrodes in my case is 60 cm silicone cable 10awg. With the same settings 40 cm cables give slightly better results. While welding you should avoid the biggest possible mistake – do not make too much pressure on electrodes. The higher pressure the worse result you get. Avoid electrodes with big contact surface. Keep electrodes under 50-60 deg angle to the surface (45 deg should also be +/-ok). Follow recommendations related to battery. I see comments where battery size was 60ah or even 100 ah. I do not think it is necessary. I used old acid battery 40ah where measured health (soh) is 66% and max current 260a. Internal resistance 11,5 mohm. I can get good results using such old battery. Hoping for long lasting life of the product. More detailed manual is needed

It works, I like it. At first, I used longer wires, but it welded very poorly. With shorter ones, it welds well at 80%.

Working excelent!
Dont try at max power, at my first attempt lucky me it was a dead cell, has punch a little hole in the cell.
For me at 55 it works perfectly.

Everything arrived intact and as stated by the seller. Tried it and it seems to work. I recommend the seller and the product.

Everything arrived intact and undamaged, but in a very unusual way; this has never happened before. I ordered 6 items, but only 2 arrived. I contacted Ali to request a refund, and they responded that the store told them they had sent everything, and the rest was on its way to me, but there was no tracking information. Later, they reached me, but they were packed in one large package along with other orders. As for the quality, I tried cooking with it and really liked it; it’s high quality and doesn’t overheat. I tried speeds from 10 to 80, everything works well, I recommend it.

The package arrived quickly in Ukraine, everything is as described, haven’t tested it yet, but the nice thing is that you can connect any external battery and not depend on the internal one. I recommend the seller and the product!!!
