I'm not the type of person who thinks product reviews should be written immediately after purchase. I rate a product by how well it does its job over a long period of time. In this case, this product will be rated after a session with the vacuum cleaner after installing the belt. The good news is that the vacuum cleaner is working well again. So far there is no bad news. Regarding the speed features offered by the Revain verification tool: Easy to Install: This is a feature of the vacuum design, not a replacement belt. It was easy enough to install on my vacuum cleaner. Value for money: I can't answer this question yet. The first strap didn't snap after the first use, but that's to be expected. Durability: Can't answer this question as there just hasn't been enough use to determine a realistic answer.
