### ⭐⭐⭐⭐⭐ Handy to have around the workshop

Excellent - recommended

### ⭐⭐⭐⭐⭐ happy with the purchase
*by P***E on 9 July 2024*

I am all round happy with the purchase, I am only using these as a faster way of re-squaring my compound and tool post, and some clamping and small repeatable setups for fabrication. happy with the quality and the case is nice too.

### ⭐⭐⭐⭐⭐ Great Value
*by A***K on 20 January 2023*

Cleaned up the blocks and they measure the imperial dimensions stated, unfortunatley on checking the unthreaded holes these were found to be the incorrect tapping size to tap 3/8 x 16 BSW, the bolts would be a rattle fit. I was hoping to tap these if required on later projects.
