Wartenberg Neuro Pinwheel Stainless Steel Diagnostic Instrument Pin Wheel. Skin Sensation Ten (10) Head - Strong Pinwheel Instruments by G.S Online Store, Silver

Bought this for freeze drying blueberries. Works OK but the blueberries stick to the spikey part. Trying to keep rolling this over them doesn't work or crushes the other berries. Good idea & take a bit of extra time to use this tool. Still better that trying to do the job any other way I've tried.

I bought this to poke blueberries for the freeze dryer. It doesn’t roll well over the berries but it pokes them very well and efficiently- it’s a keeper for me

She loves the feel of it on her skin. We bought a single wheel that she liked. So I surprised her with the multi-wheel. It was a hit.

Nicely built of quality materials. Strong, sturdy design but berries stick to it.

Great for poking holes in blueberries before putting them in the freeze dryer.

Purchased this item thinking it was high quality, surgical stainless steel as advertised. After the first cleaning, it rusted. I would not recommend it if rust is an issue for your application. I setup a return and I have to pay to mail it back to the seller for a refund on a poor quality product.

I purchased this as a cheaper alternative to the blueberry puncture device for freeze drying. It worked for that purpose though a little awkward

Probably works better for it's intended use. Doesn't really work for blueberries.
