    I ordered this after installing an Optima Yellow Top in my car. I needed the slimline version since there is an OEM fuse box just above the battery, making things really tight. This fit perfectly for my needs. The battery connection is solid. The 3 connectors are simple and easy to tighten. The cover is a very nice touch and keeps your hot leads protected from stray wires and such. I’ve been doing car stereo installs for years and this terminal connector is a good example of simplicity and quality construction. I highly recommend it.

    Well built, in my opinion. Handsome finish. Easy installation. I bought the matching Negative and Positive terminals for my setup. Both are great. I like the clear covers; they look good, and serve a valuable purpose.

    My only complaint is that it is so wide that it sticks out beyond the battery, and risks hitting a common ground. Don’t buy if you’re battery doesn’t have a bit of clearance on the side next to the post.

    I know that Monster is often thought of as medium quality stuff that tries to pass itself off as premium quality stuff at a premium price. But this battery terminal really is premium quality. At least if you are looking for a ring-terminal type of terminal. If you want a direct wire attachment, then you’ll need to look elsewhere. But for a ring terminal type unit, this can’t be beat.

    I have just one quibble, which is why I gave it 4 stars instead of 5: it is advertised as “slimline”, which it is — or would be, if the cover was shorter. The cover is way too tall for a “slimline” product, with 1/4″ to 3/8″ spare space. This isn’t a problem for my installation. But, if it is going to call itself slimline, then, it needs to have a slimline cover.

    I did, however, buy the product on sale locally for $20, which is less than Amazon’s price.
