## Customer Reviews

### ⭐⭐⭐⭐⭐ Very Happy with This Purchase So Far...
*by R***S on May 18, 2020*

This unit is everything I expected and more. Of course, I just received it a few weeks ago, but I have used it and I’m very happy with the results. I was pleasantly surprised the unit came with a very, very long Roll of nickel plated strip. The manual was disappointing - poor translation. Fortunately there are many YouTube videos that fill that gap. I wouldn’t hesitate to purchase another unit from this manufacturer and wished they made it more convenient to purchase accessories like the handheld electrode unit for larger battery packs.

### ⭐⭐ Welds
*by A***S on August 8, 2022*

EDIT: Nope did not help at all. Would have to take a part and rewind, and mount the cables directly. DIY Youtube video on this. Just don't want to spend anymore time or money..( humm time is money) on this..EDIT: Got welding tips same as -John B another customer, will give it a shot and see how it does.Ok so I waited to review this for an honest opinion. Welds are super week but I am using to two pen connecters for welding. Not the built in push up spot welder arms. Now this might be the issue. But this is not a viable set up for me or anyone. If you have any and I mean any large row of batteries they will not fit under the weld arms. If you bought this for battery building, then your in the same boat as me.. Will update with a thicker wire set up, but as of right now, this is not looking good..

### ⭐⭐⭐⭐⭐ Well designed, easy to use
*by N***H on September 29, 2021*

Have a bunch of older battery operated power tools - Porter Cable and some Ego stuff (lawn mower, string trimmer) as well as an older e-bike. Got this to rebuild failing battery packs.Only had it for a few weeks but tried it out and it works really well - nice design and works well. I specifically chose Mophorn as I have had good results with their other stuff.
