5 star rating  Looking for a North
Hector from PR
These compasses are small. I gave one to nine friends and they were delighted. I put it in the dash of the car to see the movements of the magnetic field of the planet where I live...lol!

5 star rating  Great value
Andy from Laurinburg, NC
I needed a small compass that would fit in the watch band Compas, which had stopped working. Anyway, the size was right, and when I received it from Xump it fit perfectly. Each compass in the package aligned correctly. I was surprised that all these compasses came at such a good value. On ordering them I had to check with the customer service rep to be sure I knew what I was getting for the price. I was very surprised and pleased. In fact, he showed me other products that I may purchase later. My question now is what I do with all the other nine compasses. I have lots of friends with kayaks who can use them on their boats. I’ve been doing this for years. The compass with a little Velcro go a long way. Anyway, thanks and great service.

Better than expected. Used in walking sticks

5 star rating   George from Methuen, MA
These are very nice small compasses I used a 21 mm forester bit and they drop right in, a little glue and they stay, made walking sticks for myself and family

3 star rating  Iffy

some worked and some didn't - not much on quality control

xUmp.com Reply: Compasses frequently get de-magnetized during shipping. This is why we include an instruction card on how to re-magnetize your compasses. This has nothing to do with quality control but more with postal office sorting and shipping equipment.

5 star rating  Perfect
Phillip from Indianapolis
Need a new compass for my surveying equipment. These were the perfect size!

5 star rating   Danny H. from Alaska
As advertised. Bought two ten packs. All twenty were spot on. They are sensitive to ferris metal that is near by and will react to that. When not influenced by outside elements, they work fine.

Bought them for mini survival kits. Only had one that is off.

5 star rating   Mini (Should be Micro) Liquid Compass
Mark from Anchorage, AK
Ordered 400 for use in our rural self install kits for Satellite communications so they know in what general direction to point their satellite dishes. They work great. They are just quite a lot smaller than i was expecting, but that's my own fault. Can't say I've found a defective unit yet, & they all work wonderfully.

Dave from USA, Michigan, Portland
I have several camping/survival tools, combination matchholders, whistles, compasses, and paracord wrist bands which have useles compasses. I bought the 10 pack hoping there would be a few that really worked. SURPRIZE! They all did.
