Question: Will this tool work for other blenders with similar holes in top?
Document: I do wish it would reach a little closer to the blades for blending leafy ingredients but since I blend mostly fruit this tamper serves my needs very well.Makes one of my best small appliances work even better; pleased with this purchase and highly recommended!Edited To Add - after comparing this tamper to one just ordered and received  along with a new carafe from the Vitamix Company I've been able to determine this is a genuine Vitamix tamper tool; it is embossed on the top of the tool with the Vitamix name.
Vitamix is worthless with out this device. This plain and simple piece of equipment is sturdy, dishwasher safe and essential to break up and help mix ingredients in your vitamix blender. I suppose one may use it for other blenders but the length capped by the handle at the top is sufficient to get the tamper to just above the vitamix blades without harming the device. Word of warning, don't use this tool without the vitamix cover in place. This reason alone is why we are purchasing a replacement. :)
Make sure that you know what size of Vitamix you have, because I bought this and it was too long for my model. It does have Vitamix stamped on the top, so it probably is an authentic product but just doesn't work for my model.
I broke my original tamper and having to go without one was lots of work. If you have a vitamix this is a must have tool! Thank you!
I had lost my tamper tool that came with my vitamix. It is really the only tool to work with the vitamix and I am so glad to have mine back!
This tamper tool is exactly the the original that we had but we also destroyed by putting into the blender by mistake. It is stamped vitamix on the top
Learned my lesson and keep the top on my vitamix on while using this Tamper tool. It helps with those stubborn ice chunks when I make my own version of Robek's smoothies. Very helpful!
After not using the original one ONLY through the hole in the top of the cover (which prevents the bottom of the tamper tool from coming in contact with the blades) resulting in its destruction, i found this one on Amazon at a great price. It looks virtually identical and is the same diameter and length as the original, contrary to what a few comments stated.
Perfect Fit!! Just as advertised. Would recommend to fallen hereos of the new world order,  They will use in the holes.
I inherited a VITAMIX and this was missing. Works just as it was intended to work and easy to wash.
Answer: It should.  Approximate dimensions are as follows:  Circumference: 4.5" tapering to 6"; length is 9" from guard to tip; handle is 3"
