★★★★★
I've gone through so many bag clips over the years and they always end up popping open. This actually heat seals the bag shut. Crisps are still crunchy three days later. Genuinely impressed.

Bought it thinking it would be a gimmick. It's not. It sticks to the fridge door, charges over USB-C, and seals bags properly. We've had ours for two months and use it every single day.

Stopped throwing away half-open bags of frozen veg. This thing pays for itself in a week. The six heat settings mean it handles everything without burning through thin bags.

Compact, rechargeable and actually works. Magnetic back is a genius touch – it just lives on the fridge. My whole family uses it now and nobody has complained once about stale food.

Arrived quickly and works exactly as advertised. Love that there are no batteries involved – just charge it and forget about it. Solid build quality too, doesn't feel cheap at all.

Frequently Asked Questions

Does it actually create an airtight seal?
+
Yes. It uses heat to bond the bag closed rather than just clipping it shut. The result is a proper airtight seal that locks moisture out and keeps food fresh for days longer than any standard clip.
Will it work on thick bags like freezer pouches?
+
Yes. With six adjustable heat settings it handles everything from thin crisp packets right through to thick freezer bags and foil pouches. Just select the right setting for the bag you're sealing.
How long does a charge last?
+
One full USB-C charge delivers weeks of daily use. The cable is included in the box. No AA batteries. No running to the shops mid-week.
How long does delivery take?
+
Orders are typically dispatched within one to two working days, with delivery taking a further two to five working days. You'll receive a tracking number by email as soon as your order is on its way.
Is it easy to use?
+
Very. Hold the button to switch on, select your heat level, run it across the bag. That's genuinely all there is to it. No instructions needed after the first time.
