Yes, it works! And it's quite helpful.
But it takes a little experience - the right temperature is key! Not too few and not too much heat.
And it takes much more heat than just for shrinking the tube. Things around must be protected.
Well packed. Fast shipping
Everything is super, it came quickly, tried to work perfectly, only to warm it is necessary with a hair dryer, it melts with a bang, it's a pleasure to work, I advise for 100%
