United Scientific Tuning Fork Set of 13 with Dual-Ended Mallet – 13 Aluminum Alloy Forks in Wooden Storage Box – For Sound Wave Physics Science Experiments – Frequencies 100 Hz to 4096 Hz Tuning Forks

I absolutely love this set, the tones are clear and I become very calm when meditating to these frequencies. I discovered I had a slight crack in the plastic lining that’s holding the turning forks in place upon arrival, however it’s a small price to pay and I would definitely buy this item again.

This is an amazing value for the price. All the forms are fitted into the box nicely along with the Malloy and each had good resonance. The box itself, while cheap locks and hinges, is absolutely fantastic for the cost. What they saved on outer materials, they made certain the forks and hammer were secure. Great product!

I gave 4 stars ONLY because there is NO manual. The 13 forks are precise and well built. The mallet is sturdy and good too. I'm just a big baby and want everything (manual) at my finger tips. :-) Give me a manual and I'll give you 5 stars!!

These were for my grandson and he absolutely loved them

I got these the other day. The box it comes in is a bit flimsy, but still sturdy enough. The inside where the forks sit, is plastic and cheap. I was disappointed in this. Testing the forks themselves, all of them but the smallest one work decently - except they all don't sing AS long as they should be doing - though some do. The smallest one barely sings. You have to hit the fork several times to keep it going. I'm sure practice using these will help, but I'm not sure if I really recommend it yet. For the Price it's a good starter kit, especially for musicians. I don't know about healing sessions. There are only a few of these that were therapeutic. Combining them especially will drastically improve the overall session for healing.

Great value to use as sound therapy/healing tuning forks! There are a couple that don't make sense for my purposes, but the value is unbeatable for the ones that do. Wood case is lovely. Plastic insert is flimsy (but I don't use either, so I don't care).

EXCELLENT! I had doubts because of other reviews but no...this works nicely. Package came in very well packed. I used it right away on myself and trust me...a subtle treatment does a whole lot of work..just a couple of minutes is good! The hammer has a buffered end (black) for softer treatment (response) while the othe end for stronger treatment (response). The box is very nice and I recommend one purchase this at this low price (compared to other way expensive models).

I enjoyed the several sounds of the tuning forks, that was a great shop. I just would like to know more about how to measure the frequencies of every fork, it seems to me that they are tuned in other values, but perhaps is not based on the 440hz, but lower.
