Review: Powerful but mine arrived in a horrible state. - I can't speak of the product's durability but, after all, it is metal and has nothing on it that I can see to wear off or wear down. It should, therefore, last a lifetime. The value for money seems to be first rate as long as it continues to perform as a magnet. The magnet arrives in special packaging which is required to prevent it from harming anything that might come into its proximity; magnets can, for example, damage electronic components. This packaging is basically two, presumably lead, halves that together form a box around the magnet. This is fine but the ones I got were covered in some horrible, thick, grease which served no apparent purpose (nor did anything in the written documentation refer to this grease). So, I had to clean it off using a special detergent. Once done, the metal storage 'box' was fine. Buying this magnet was an education for me. I learned of the existence of magnets of such power as to be physically dangerous although this particular size could hardly be dangerous to an *adult*. Be in no doubt as its power, however. I thought it might be a good idea to make the side of my fridge freezer its home. NOT A SMART MOVE! In the first place, once stuck to the fridge, I couldn't remove it without great difficulty, having, in the end, to slide it off sideways! Secondly - and far more importantly - my fridge broke down within about a week. This may just have been a coincidence as it had worked for over 20 years but then again, after being so reliable, maybe it was the magnet that finished it off. So, beware! It is powerful.
Review: SELLER IS TRULY AN EXPERT ON MAGNETS - HUGE CHOICE & FULL DETAILS - Expertly packed with full warnings in multiple languages, this extremely powerful rare earth magnet must be kept away from computers/credit cards/anything with iron in it. Neodymium is the rare earth included in this magnet. Heed the warnings and remember your blood contains iron - unless you are an expert or are willing to take the risk - only place the magnet very carefully. Avoid contact with any metal implants (heart, teeth, spine, knees) should be avoided. Fun to see the magnet 'leap' toward the plastic coated iron container. Website gives the weight that these type of magnets can pull - you will be amazed ! Highly recommend the sellers website - like the packaging and information on the product, it is exceptionally well organized and works very well indeed. There are some fun things for youngsters including a magnetic 'putty' - tons of stuff both useful and fascinating, many half price offers too. Just use their username and put dot co dot uk to visit the site. I've bookmarked mine. A rare treat to be able to praise sellers so highly - and a fully functioning website shows these truly are Magnet Experts.

### ⭐⭐⭐⭐ Useful for finding screws in plasterboard
*by M***N on 7 January 2022*

Nice and powerful, I keep mine in the plastic case that they provided (I discarded the metal box). When it finds a screw in the plasterboard, the magnet will happily stick to the wall if you let it.
