Communication

I need help. I'm trying to solve this comm issue for my son and keep striking out. I copied and pasted as much info as I've collected, but basically it connects and then disconnects if I try to do anything. It seems as the ezb4 forces the connection to close, but the computer connection still shows the connection active.

It seems like we answer this question at least once a week. I would suggest increasing the dev kit cost and just including a LiPo, charger, and harness, or at least moving them up in the "related items" tab when you view the dev kit in the store. Maybe even prompt shoppers to add them to the the order like Amazon does with their "people who pirchased this often also ordered" prompt.

It's been considered - and the related items does exist but should be more prominent during checkout. Although that only solves ezrobot customers, not resellers.

Price cannot be altered and the product cannot be changed without a new sku/product due to registered msrp agreeements.

Something will happen if issues rise above 2% of sale volume. That's the threshold to consider change.

I didn't think about the re-sellers, although you could provide them guidance, no way of enforcing without a new sku. Even on the related items tab, it could be more prominent. It is at the bottom rather than top of the list -- just saying.

Just curious, and you don't need to share if this is considered proprietary, but what percentage of your sales are direct vs re-seller?

Good to know you have a plan;)

:) there is an internal process for everything

Not sure an exact percentage but it's quite high. You may have noticed decreased marketing attempts, where ezrobot used to create lots of videos and such to encourage direct website sales. Now we spend those resources on retailers and supply chain optimization for localized geographic sales. In many cases, it is too costly for people to purchase direct from our website when they can purchase local.

To answer your question, we focus on resellers and distributors more than our websales.

I should add that situations like this original poster is a good thing for the community. Without it, this person would have never visited. Rarely does anyone visit the community for something other than assistance.

Every one of you came here looking for assistance - some stick around and many go on their merry way. What ever the outcome, the prelimary reason is always the same.

And I learn from every post:D

Do any of your Canadian resellers sell your LiPo batteries and charging units? I've been looking around but can't find anyone who does.

Robotshop sells batteries but not ours
