I took this on a 3 week solo trip through Japan moving between hostels every few days with just a backpack. Space is everything when you're living out of a 50L bag and this pump genuinely changed how I packed. Compression took maybe 6 seconds per bag, the pump is whisper quiet which matters a lot in a shared hostel dorm at 6am, and the bags held their seal the entire trip. Repacked probably 15+ times and not a single bag failed. If you're doing any kind of backpacker-style travel, stop overthinking it!
Just got back from a 10 day trip to Europe and this thing saved me so much space, and money! fit everything into a carry on and avoided $90 in baggage fees both ways. The USB-C charging is really convenient, just charged it from my laptop before the flight. Takes about 10 seconds per bag to compress. Already told all my friends about it. Will never travel without it again.
