Nothing wrong with parrot nippers at all. Everyone has their own method to increase a hole size. But take a look at the precission you can achieve without a nibble.
Now this one below is spot on. So good in fact the customer took off the cowl normally used to hide scruffy nibble work. Thats just silicone in the joint.
And then see this one. The cap has been pulled back to reveal another perfect hole but without any silicone. Thats a 16mm bore with a 15mm rad pipe.
And again on this bath tap. A 30mm hole but covered with a plate. The plate has been pulled back to reveal the fitting. Again no silicone. If silicone was used it would look as great at the top one.
Its pression stuff done in a few mins into very hard and very expensive porcelain tiles fitted to the wall. (You dont want to be breaking them on the wall ! ) And with this contemporary type of minimalist look the customers love to see a bit of accuracy. Especially when they can pull back cover plates to see whats behind. And they do look !
Yes Parrots have their place. Yes there are other ways to open up a hole. But in my opinion (and its just my opinion) ya cant beat this sort of job presentation to your customers. Its top end stuff and what they will be looking at day-in day-out for years after.
I've posted on other pages that we offer a 100% money back if you think our kit is a load of old rubbish. Of course its not so please try them.
