Strong well made but ..
Color: Gold
Coring tool broke as soon as I tried to loosen the top. As far as a tube goes it is great. Seals tight, solid Aluminum throughout. You could throw this off a tall building and it would be fine afterwards.

I love this thing!
I can't overstate how much I love this thing! As someone who enjoys a good cigar on the go, I've tried various single cigar cases, but this one is in a league of its own. First, the build quality is outstanding. The aluminum alloy feels incredibly solid and durable in your hand. It's clear this was made to last. I have no doubt that my cigar is perfectly protected from being crushed or damaged when it's in this thing. The convenience factor is a 10/10. It’s sleek, compact, and makes carrying a single cigar effortless. But it's the brilliant integration of accessories that, for me, truly sets it apart. Having a sharp, reliable punch built right in is fantastic. The built-in hygrometer gives me total peace of mind that my cigar is staying perfectly fresh, and the clever design that allows the top to double as a cigar holder is just plain genius. This tube is the perfect, all-in-one solution for any cigar aficionado who travels or simply likes to be prepared. I'd recommend it to anyone without a moment's hesitation. Five stars all the way!

Nice light saber handle with some room for a cigar lol
I'll go straight to the point: this cigar tube is great! I really like the material, it's made of thick aluminium and it's design is both classy and nerdy at the same time, it looks like a jedi light saber handle lol The hygrometer seems to be accurate, close to my other ones, it's a nice extra functionality. The size of the tube is big enough for my largest cigars, so all good here. I recommend it, either as a gift to yourself (because you deserve it!), or father's day, or any good occasion!

does the job!
I bought the DXXULL 4-in-1 Cigar Tube as a gift for my husband, and overall, it’s been a solid choice. He travels often and enjoys cigars, so this compact, all-in-one tube really suits his lifestyle. The aluminum alloy feels sturdy and well-made, and the built-in cigar punch, hygrometer, and holder add a nice touch of convenience. It’s sleek and functional—he’s used it several times already without any issues. While I do think it’s a bit overpriced for its size, the quality and thoughtful design make up for it. If you’re looking for a practical, stylish gift for a cigar lover, this tube does the job well.

won't fit Churchill length or 60-ring diameter cigars
Color: Gold, Color: Gold
This is a good-looking device, solidly built, with a handy twist-out punch in the top and a humidity gauge in the bottom. The hygrometer is pointless, because there is no way to add anything to actually maintain the humidity, and since I would only use it to bring a cigar to a gathering, it really does not need to maintain that humidity for the 20-minute drive. What really bugs me about this is the actual useable size. I primarily smoke 2 types of cigars, 54-ring Churchills (which are 7") and 60-ring Gorditos (which are 6"). Although the overall length of this is 8 1/4", the listing never mentions the interior space, which seems to be just under 6 1/2" when closed. My Montecristo sticks out about 1/4" when I insert it, and that does not take into account the 1/4" that the top pushes into when closed (that silver-colored area is solid), thus less than 6 1/2" useable length. Even out of the wrapper, my 60-ring Gorditos sticks when I try to push it in, so I'd have to take off the band(s) to force it in, and it would not slide out very easily, so I would mangle the cigar trying to get it out. So, this can hold a cigar that is 6" or less and maybe 54-ring without the wrapper. Anything else, and you would have to force it in and force it out. So, this unit, while very good looking and well built, does not work for my cigar needs.
