I've made my feelings known about Matchbox kit quality, or lack there of, many times before on other forums. I am always amazed at their defenders.
Like many on this board, I grew up building those as well as Airfix, Heller, Revell, Monogram etc., so I owe Matchbox for cutting my teeth in my youth, and the nostalgia angle. Other than the fact that some subjects are only available by that manufacturer, or were until recently, I can't share that view today.
I'm especially chagrined to open a Revell box hoping for a new mold release, only to find one of them instead.
Never the less, you pay your money and make your choice. If you are happy with them, cheers to you.
