Does what it should
Tool works as it should, don’t use stop it didn’t make the job easier but if you have never done any crimping it should help to get started. This tool should last for years keep it out of the weather in a case and oiled you should be gold! Good crimps, release works if you get stuck, the grips require a good sized hand to work smoothly, this is common with this kind of tool

Great crimping tool easy to use
Purchased this so I could connect my own solar panels with the wiring. Its easy to use and clicks when it crimps. It has comfortable grips. It is lightweight and durable, works well. Price is fair price to the market.

The extra terminal depth gauge doesn’t work
Paid extra for the crimper with terminal depth adjustment. It does not work. The barrel is too small for the MC4 female terminals, and was misaligned for the smaller male terminals. With the depth adjustment removed, crimper worked great. So still 4 stars, but save a few $$$ and get the same model without depth guide

Works perfectly and great value for solar project
The crimping tool works perfectly and is a great value, would not hesitate to buy again if needed another one. Used for crimping 10AWG wire to Staubli MC4 connectors and it was easy to use and made perfect connections.

Well oiled, definitely worth it for the price. Makes professional, extremely tight crimps.
Amazing results! Tried pulling with all my force (I bench 200lbs) and didn’t move at all. Well oiled tool. Takes some learning to use, but it gets the job done well. Makes professional grade crimps every time.

Tool works good, except for the guide
Tool works good, but the attachable guide doesn’t really help much (which is the main reason I bought this one). I ended up buying an expensive high end crimper to avoid any issues.
