Hi Beeks … does anyone have any experience with this product or anything like it?

From the ebay description:
"Easy to use. The herbal oils are fed in a sugar water mixture.
A binder made from soybeans, which is a super food for honeybees, is used to bind the sugar water feed and the essential oils."

Anyone that calls soybeans a “bee superfood” is not to be taken seriously. About 40% of sugars found in soybeans are toxic to bees.
Bobby’s right. There’s a lot of snake oil on the market for the gullible. All bees need is a varied diet just like us really. There are a few reputable and proven treatments on the market if the need arises.
I share something with bees then, all of those oligosaccharides and fructans (both types of sugar) in soybeans are toxic to me too. 
Ok, thanks for the comments everyone, I’m leaning towards oxalic treatment then and this unit looks not too bad; not the cheapest but looks sturdy:

Good choice but get a good unit.
This one has held up nicely and it’s not flimsy like some of those cheap models:

With 50+ hives, it’s too time consuming so I just sold it and got the JB-700:

This is the unit I use as well. Two treatments this year and zero issues.
