As a hesitant buyer, I was a bit unsure about these Uninsulated Terminals but they definitely did not disappoint. As my tests showed, they are incredibly easy to work with and fit perfectly with my wiring needs. They are also quite durable and will last the test of time. They are certainly a good investment for any industrial and scientific purposes .The only con is that they are a bit pricier than other similar products on the market, but their quality makes up for it..
