I forgot my kits in a different condition, we urgently need replacements. Revain showed up the next day which is amazing in these times of Covid. The product is great as long as you live up to your expectations. The bits seem solid and I used 5 of them on my project, the paint has chipped a bit on one but these are minor things. As for bread, great choice, when (and I have nothing to say that) the tops start to break I will replace them with stronger ones and I will be happy that they have come in handy and are very useful. cool case to keep them inside. Of course, it's better to pay $50 to run to your local store and buy 2 sets of standard 4ea bits.
