Sanrenmu GJ039Z Multitool

I bought it out of curiosity during a promotion and I'm pleasantly surprised. Very useful and convenient, perfect for keys or a carry-on bag. A mini crowbar and several other functions. An interesting little gadget.

A light and cool gadget, works perfectly as a keychain. You don't feel it when carrying, and it's always at hand when needed.

I wondered whether to buy such a small tool, but ultimately its compact size and lightness turned out to be great advantages. I was looking for a solution for unexpected needs to loosen or tighten something outdoors and this gadget works great for that.

A practical and inexpensive gadget that works perfectly as a keychain for any set of keys. It's durable and sturdy, so you can even lever something with it. I recommend trying it.

It doesn't have unnecessary extras, such as serrations pretending to be a saw (I sympathise with those who had to file such a thing). The product does not fully match the photo – it's missing a nail puller (what will I do now ;-)). I also don't know where the hex key is. I hope the rulers won't wear off. Overall, a cool keychain with a few useful options.

A small, durable and practical gadget for a reasonable price. High quality workmanship. A very useful ruler in inches and centimetres. It's light and could prove invaluable in a crisis.

A very solid and compact keychain. You can attach it either to a keyring or directly to the keys. It's already proven to be indispensable several times, for example to unscrew something or open a bottle. It doesn't take up much space and is very practical, well worth having for years.

Small and very useful in different situations. It works great with Allen screws. It can even be used for self-defence – as a kubotan. I especially recommend it as the price is very affordable.

A very useful keychain, well made. I always have it with my keys. It offers a lot of practical functions, and the large ring makes it easy to attach keys. Small dimensions are a big plus. Brilliant.

Great keychain, carefully made of durable stainless steel. It can be used as a small tool in emergencies, e.g. to tighten loose screws or nuts, open bottles, pull out nails, or even to measure small items. Perfect gift idea!

A very handy and sturdy mini crowbar. Excellent for keys.

Solidly made. Suitable for minor tasks like screws or opening bottles. Perhaps a pictorial manual would come in handy.

A useful gadget that I always have with my keys.

Small and practical.

Small and inexpensive. A solid ring, resistant to scratches.
