### ⭐⭐⭐⭐ 







  
  
    Definitely A Good Value For The Price
  

*by M***W on Reviewed in the United States 🇺🇸 on February 11, 2023*

I mean it's a terminal block and it works as proclaimed. I wouldn't try to test the 65A rating as I'm pretty sure the contacts and the plastic mount wouldn't survive the conditions. It's also not a protected block so whoever is putting the ratings for this in the comments isn't doing the consumer any favors. All in all, I needed a small block that could handle the job in a tight place and this was the perfect size. Cost was more than fair for most other options and quality was better than some higher priced alternatives as well. Cannot complain.

    Nice Terminal Blocks, BUT...
  

*by J***K on Reviewed in the United States 🇺🇸 on July 19, 2015*

Pictures can be deceiving... 'Especially' when the description falls short of providing all the details that one needs to make a choice.This terminal block is actually really small! After I received it, I had gone back to amazon to look at others listed. It seemed that all I had found, were all by the same seller.I opened up 'several' listings, went to the descriptions on all of them, and found the same exact thing.Or should I say, the 'lack of' the same thing in all the descriptions. That being the 'screw size' in the terminal blocks.I've used these types of terminal blocks for 'many years' now, and have seen them in several different sizes.And I'm not talking the 'number' of terminal connections, but in the 'screw size'.And the screw size 'directly reflects' on the spacing in-between each terminal connection, (and the little dividers in-between the screw connections).And that'extremely important when you have a certain size terminal connector, you want to put under the screws.I had discovered that this 'particular' terminal block uses #6 screws.These are well constructed terminal blocks, (most likely still made of bakelite), which provides for an excellent insulator.I'm deducting 'two stars' just because of the lack of a through description along with the listings.I did talk to the company, and they do offer these terminal blocks in various different sizes, (besides the #6 screw), and I'll most likely order exactly what I need through them.However unless they can give me the 'particular' amazon listing, with the correct size I'm looking for, I'll be forced to order directly through them.And probably either needing to come up with a minimum order, or paying more in shipping than the item itself costs.

    Just what I needed!
  

*by R***S on Reviewed in the United States 🇺🇸 on June 1, 2022*

I used this in my bus conversion to replace a rusted terminal bar. It was exactly what I needed!  I am a very happy customer!
