The 140PCS Butt Connectors Heat Shrink have been essential for my electrical projects. With their waterproof design, they ensure secure connections and durability in any environment. Ideal for marine and outdoor use, these connectors offer peace of mind and reliability. Highly recommend for anyone tackling electrical projects!

This set includes a nice selection of connectors for various wire sizes. My initial testing was stressful on the connectors and centered around the smallest connector which is normally quite challenging. I got a good crimp on, although the standard crimp tool almost everyone has doesn't quite cut it, so I needed to use a pair of pliers. When performing the heat shrink I put wayyy too much heat on purpose and it held up quite well; the wire's coating melted first. When the heat shrink cooled it provided a very good level of seal around the wires. For the quality and cost these are a great buy!

Good value for a nice assortment of heat shrink style of butt connectors. No complaint about the connectors themselves. Small complaint about the case -- of course it's a cheap case, I understand that, but I do feel that it is a huge oversight for the case to not have a pegboard hanging hole on it. Every other electrical connector kit case has a pegboard hanging hole on it, so I will have to improvise here.

Excellent quality Waterproof Butt Connectors. *If the specs allow this type of connector these Denninal brand connectors are a good choice. *This set is service call friendly. *If you need this type of connector for a home or car project these Denninal connectors are a solid choice.

As far as the splice connectors go, it was nice seeing 4 sizes in a kit. I also like the heat shrink feature on this style of butt-end splice. While not mentioned in the product description, the copper part of the splice does appear to be tinned. Overall, this is a decent set of connectors. For heat-shrink, waterproof connectors - this quantity at under $10 is a pretty good deal. I'm a little disappointed in the case. Clearly the 11-pocket case is generic and not really made for this particular set. Mine arrived with the whites mixed across three bins - which was not easy to resort. The reason for this mixing was obvious when I tried to put them all into the front center - they don't fit in that space. A box with 4 correctly sized compartments would have been much better. This case, with the small compartments, also makes it difficult to grab individual connectors - at least with my large fingers.
