I already had an older but unused pair of another brand which appear identical except for the handle colour.I had a project where I needed to do a little over four hundred crimps for a new flight simulation controller box.After a couple of crimps I thought things weren't going too well and while I expected it was going to be fiddly with such tiny connectors, I expected a better job.I decided to buy this pair even though I thought they looked the same and I could more than likely be wasting my money.When they arrived (very quickly) I examined and compared the jaws with a high powered magnifier and the was a slight difference.These are so much better.I had to redo just one out of 400+ crimps and that one was my fault.Yep, I recommend these!

El perfil del crimpador hace dificil su uso para terminales dupont. no recomendado.

Crimping in general is a learned technique, and I found that squashing the joint a little with the tool prior to inserting the wire helped the quality. There are adjusters in the tool, and I am not sure my joints are 100% yet.

Used properly this tool works great. I purchased this tool to make some 2.54mm Dupont cables. It is not a strait forward process with such small connectors, I looked at various tools listed of the SN-28B model (which is the proper tool for 2.54mm Dupont connectors), and all appear practically identical with very mixed reviews. These connectors are designed for a machine to hold onto that back strip that you break the connector off of, and since you take it off to do the connections with a manual tool like this, it gets rater awkward. Based on what the connector specs are, you only strip 3mm of insulation. While I have seen various uses of a "multistep crimp" approach where you do a partial crimp to get the shape easier to work with and even do the bare wire with one crimp and then the insulation section as another, it can be done in one step and I believe it was meant to. The 2.54mm Dupoint is done in the smallest of the 3 sizes on the SN-28B marked on the one side as 0.25 and not the large one that is marked 1mm (I expect using too large a slot will overly flatten the connection or not end up with a tight enough crimp or both). It seemed best "not" push as hard as you can, just go until it barely releases the ratchet as to not smash the connector, even at that with the wire I used it was slightly wide from being crimped. I carefully used pliers to narrow it back. These are small and delicate connectors and a hefty tool with enough force to wreck them if you over do it. Also putting them in upside down or not aligning them properly would easily wreck them. The two crimps I did to test the process and tool both worked perfectly. See in the pictures as assembled and in the one with the Red one I did beside a factory done one on a white wire. I found a very good video over at youtube titled "Using IWISS SN-28B Crimper" which is virtually the same tool, but if you watch it note that the dies (crimp head) are installed in reverse on his tool compared to the Glarks model I received today. His process seemed to be a very good approach and likely more inline with the intended usage than "multi step" methods I saw being suggested, which on their own may work very well too. Also the ratchet can be released by that little lever on the short handle side that comes out when it engages as it is closed (incase it slips you Can back it off and maybe save the connector rather than hopelessly smash it)
