I use this with my NS-Design CR5-M electric upright bass when I have the endpin stand attached, and find it to be essential as it converts the original tridod stand that came with the bass into a stand where the bass can be easily kept safe after the soundcheck and between sets. The two parts making up the kit are well engineered and are both very easy to attach and remove. The kit may seem rather expensive for what it is, but as it can help prevent the bass from being damaged between sets when the endpin is in use, it only needs to prevent the bass being damaged by falling over once to more than pay for itself.
