## Questions & Answers

**Q: If i stacked the magnets together would the pull be multiplied ? Thank you**
A: Not by very much if you put one on top of the other. Side by side, two would exert about twice the pull of one.

**Q: Will these be strong enough to hold bottle tops on a home made bottle opener board**
A: Good morning, thank you for contacting us. Provided that the bottle opener board is a mild steel surface, these would work extremely well. Although they are quite small in size, they are very powerful.

**Q: If I was to drill a small hole in 1 and and attach cable to it could it work between plaster board to help pull cables?**
A: I understand what you mean but I suspect that the strength of these magnets will not be enough. Do not forget that Plasterboard is usually nailed onto Wooden Batten Frames .... If you wanted to drop a cable top to bottom inside plasterboard why not drill your hole high-up, drill a hole lower down .... tie a small nut (or something) onto a piece of fine string .... drop it from inside the top hole ...  hook it out from the bottom hole (with some stiff wire) ... tie the cable onto the end of the string and pull through until you have the cable.  It worked for me.  To route a cable horizontal you will have trouble when coming across the Wooden Batten Frame.    Probably.

**Q: Can you use these in the car to hold your mobile phone**
A: Thank you for your question. 

These magnets should work well to hold you mobile phone onto a steel surface or the same magnet attached to your car. 

I hope this information helps.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Super strong magnets
*by T***M on 18 October 2016*

Great magnets, incredibly strong, hard to fault. (Just be aware that they come in a plastic case and are surrounded by small rectangular metal bars to protect them in transit - I initially thought I'd been sent rectangular magnets instead of round magnets and nearly sent them back!). I combine these magnets with Sugru to open up a whole world of possible uses!*Disclaimer*: I never write reviews in return for products or discounts. Every review I write is for a product I have paid full price for and is therefore entirely my own opinion. If you are concerned about whether or not a product has genuine reviews I suggest you use fakespot.com to assess the quality of the reviews

### ⭐⭐⭐⭐⭐ Very strong
*by K***E on 6 February 2020*

Did the job but a bit awkward separating them

### ⭐⭐⭐⭐⭐ Good Magnetism
*by R***N on 18 June 2021*

Size is good as is the magnetic power. Great for magnetic white boards when superglued to an attractive 20mm plus Pin.
