On Amazon, 4 and 5 star reviews account for 91% so my experience is comfortably in the majority and I don't see luck being involved.
My video demonstrating the Sealey VS820 has 150k views and I don't recall any comments about its quality.
If negative comments exist, they're in a tiny minority.

Many of the lower reviews on Amazon clearly don't understand how its used and some reviews even blame sharp edges on their master cylinder damaging the Sealey rubber cap seal like that is the Sealey's problem.
You can also tell from some of the the Amazon reviews that they are clearly not talking about the Sealey but some other pressure bleeder instead.

Not ideal but sometimes you have to bite the bullet for long term peace of mind assuming you're in it for the long term.
I had a big spend on brake components 5 years ago and whilst it was a little painful at the time, it's still one of the best decisions I've made.

My philosophy is that if the bleed nipples are that badly rusted in, then they obviously haven't moved for a very long time. In which case that brake fluid can't have been changed properly for an equally long time. This means that there's a very increased chance that the caliper cylinders and pistons are getting corroded anyway, and are probably not far off the point where they'll stick and cause major problems. So you might well be doing a very useful piece of preventative maintenance if you do replace the calipers, while doing it have a good look at the flexi hoses too as while the system is drained down......

I've found calipers not too dear on an exchange basis, I've never had an exchange refused at my local motor factors due to seized nipples either - if you do, take it somewhere else.

Simon/ Luxobarge - wise words. At this point, I'm not sure if this is a long term keeper or not and I guess my path through this particular situation will lead me to the answer one way or another. Thanks everyone for their input.

A little bit of heat and a proper hex nipple spanner will remove the most stubborn seized nipples

Yes! These are very handy for brake nipples... Commonly known as "Flare nut spanners", I believe.

Yes, "Flare Nut Spanners". Just couldn't remember the name at the time of posting. Don't have a set, just odd ones I have picked up over the years, but well worth paying for half decent ones as they fit the hexagon better than an ordinary open ended and are less likely to round it off.

That's not true. I bled the brakes on the mini before a track day last September. I bled them again just before another track day at the end of last month and one rear caliper nipple was seized solid. A job I still need to sort! However, all 4 nipples on the rear calipers of the V70R were free and came undone easily, however the slider on one was rusted solid!

Today's exciting update - I've got one freed off - C'MON!!!

As long as its a top one, that's good enough!

Drill bit and a blow torch almost (!) never fails. Has to be a tight fit and you heat the drill bit sticking out the top of the bleed nipple to save using direct heat on the caliper. You then cool it with water and repeat until it frees off.
