Tough to Close

Posted by Verified Buyer on November 27, 2017

Solid construction. There is No fear of binder splitting apart because of to many pages inside. However, when full you have to guide the rings with one hand to meet in middle while pushing tab close lever ever so slowly so they will meet. Also there should be 2 tabs (top & bottom) to insure full LOCK closure. For the money it should be there. Maybe diffrent rings might have helped, but I doubt it.

Just what we wanted

I bought 2 of these binders to house our procedure manual at work. The rings close very tightly and don’t slip when using the product. Most importantly, the sheet protectors turn beautifully without snagging. It took me 2 years to discover this product but it was worth the wait. It is built like a rock and will surely outlast my professional career!

Good Value; Great Product

Will be using the binder daily, so ease of putting pages in and out was a consideration, along with durability of the binder. Is working great for what we wanted. The quality is great, opening/closing is good and I believe that the binder will last for as long as we have need for it. Would recommend highly.
