Cup Turner Accessory Kit for Crafts Tumbler, 2 Cup Gripper Inserts and 1 Arm Wand, Fit 20 oz to 50 oz Tumblers, Universal Compatibility Turner Attachment for Tumbler Spinner Machine

I was eager to try this, but have only found frustration at this point. I will be the first to admit that this might be user error. I have only tried to use it twice, and the first time the cup may have been too heavy for it, not sure, but it is literally the same style as shown in the advertisement. I couldn't get it to grip at all, and I thought we were good until i heard a horrible noise from the craft room and the cup had somehow slid off, big mess, ruined two other projects during the process. I have been doing this for awhile now. This isn't my first new product, mostly I am just not a fan, and I just haven't used it successfully yet. I am working up the patience to try it again, will set up video, and update my review.

I dont think it hold the cups straight enough .

Better than the pool noodles and footballs. Will not use anything but these.

I've decided this is the best product to keep your tumbler level and solid. However, the package includes 2 springs and 1 arm. I've been able to adapt it, but it would have been easier receiving 2 arms. Seller is aware of the issue so maybe there will be a time I can purchase additional arms (I purchased another set because the spring is wonderful!).

They fit any cup. Great idea but the ease of taking them on and off the turner, you need to unscrew from the turner or the part that goes into cup. The poles that come with it are short so if want li get you will need to drill holes. Other wise these are really a great idea and I wish brinier to use.

Concept is good but does not fit on to my 1/2 inch pvc pieces as i have a homemade Turner.

I only gave this two starts because the concept is great but the item does not function well. While rotating there is not enough support inside the cup and creates a very uneven spin. It may look perfect starting out but once it rotates the cup slants drastically. If they ever decide to make it to where there are 4 pressure points instead of two, this would be perfect, and I would buy again. Definitely returning this.

One of my favorite inserts! No slip grip. Just has to be permanently placed on the bar of your turner.
