I like the mini sewing machine; at first it sews well, after adjusting a few garments it got stuck. Unfortunately, without a Czech manual, I don’t know how to fix the problem.
Tested M2068G L/XL Blue: fits well, no leaks, straps tighten easily. You can snorkel and dive with it—has a valve preventing water entry through the snorkel when diving. Includes a camera mount and earplugs. For travel it can be quickly disassembled and takes almost no space. For the price it has no competition and matches the so‑called branded ones for 1000–2000 (they’re all Made in China anyway). I bought 6 pcs on sale (192 CZK each) for our whole group and can recommend it 100%.
