BESULEN 10PCS Car Battery Post Terminal Shims, Auto Lead Terminal Shim Caps with 12 Piece Washers for Top Post Battery Post Ends Repair, Universal for Vehicles, SUV, Truck, RV, Boat

They work fine. Better than the old screw method. You get full contact to post and them to connector. Recommend you coat with a dab of dielectric grease on post and outside shims and on top. Great for the money

Work perfectly to get my old battery going. Just needed to tighten the negative terminal, this is the way. I haven't used but one, they paid for themselves the first time.

Useful doo-hickey's to prevent my wife's car's positive terminal from loosening up in cold weather. Worked fine.

Nice product

Exactly as listed, super easy install, fit tight, works well, thick enough to keep food contact.

Great product you get exactly what you want. Good price.

This does not fit. The metal is too thick & the diameter too large. Installation requires significant modification.Mods include:Cutting the shim in halfClipping the shim edges to reduce the diameter & piece the two halves togetherSanding the shim rough edges that result from the clipping operationStretching the battery terminal to enlarge the diameter to fit the sheathHolding the modified shim in placePounding the battery terminal onto the post + sheathSqueezing the terminal around the post + sheathinstalling the terminal bolt & nut.What should have taken 30 seconds consumed 30 minutes.Would not recommend & would not buy again.

I always struggled keeping a tight connection with my battery cables, but these have fixed that problem. These are a game changer if you have that one vehicle where you are constantly tightening the cables or trying to twist them to adjust. I haven’t had any issues since I installed them.
