300PCS Heat Shrink Connectors - Sopoby Heat Shrink Spade Connectors & Bullet Connectors - Female Male Wire Connectors Electrical Terminals Crimp Connector Kit

I am not happy with the grip pressure. In my opinion both the spade and bullet connectors that I received, do NOT have enough grip.Before connecting them for the first time, using small pliers, I had to gently nip the gaps a little more closed. This was done to the sides of the female spades, and the tubes of the female bullets. Great care must be used when nipping these gaps more closed. Too much pressure could ruin them.This step I found necessary to have a more secure grip at the connection. Only after manually adjusting these gaps did I feel the connections were perhaps secure enough for my liking.Without this step I feared the connections could come adrift. Or worse, the yellow 24amp connectors that I needed to use, may have caused arking and heating.When crimped correctly with the correct crimp tool, the tube BUTT connectors are fit for purpose. I have used these butt connectors where needed.The shrink to fit insulation worked as it should. It appears it may provide good splash proofing, but I have no need for this feature in my application. So I have not tested that benefit, or proven lack thereof.At this time, for this solar-charging quick-disconnect point, I have abandoned using these spade and bullet connectors. This quick disconnect point was to be a way to easily remove the seat with its fitted charge controller, and then easily access the battery in my travel trailer.I will rethink this part of the project, and may use military style Amphenol or similar connectors. Or other spade and bullets that I feel I can trust.

Was excited to use but did not end up working for me. Wire would remain loose. in order to hold wire secure wrap would be damaged despite using correct tool for crimping and adjusting ratcheting pressure. Felt the connection between male and female also not secure enough.

It's good for price. Too soon to see how well they stay connected, but one issue i had was that teying to push the 2 connector together will bend one of the connector at the thin part. You have to be careful about that.

Cheap but you get 300 pcs (150 connection..

these things are total junk, I ended up throwing them in the trash since the return widow has closed, very poor quality thin metal that doesn't grip the wire and the "heat shrink" doesn't shrink well. Save yourself the trouble and skip these.

These are amazing thats all you need to know.

Fair product, fair price. Get what is shown and they work as described. Seem like they will last and are easy to use.
