Review on Padlock Hanayama Metal Teaser Puzzle by David Weis

Great quality and they definitely will not leave you indifferent! Of course it depends on the difficulty but I mostly bought 4th and 5th and they definitely kept my husband stumped for much longer than any other similar puzzles. He still has to decide a few! I have them on my coffee table and guests always take them to taste. They have an essential effect and are intended to stimulate thought. The puzzle just doesn't get disassembled - you have to keep putting it back together, which is often more difficult. I have used them as stockings at Christmas and also as a small gift of a gift card or cash. I probably bought over a dozen. It is useful to check the ratings of specific puzzles as it seems that not all puzzles rated in a given difficulty category are of the same difficulty. For example, 4 can sometimes be harder than a specific 5. I guess it depends on the person, but I found the reviews helpful in that regard. If you have a jigsaw puzzle expert in your home, they won't disappoint. And I suspect the lower levels are probably great for beginners or just to get your feet wet.
