Having seen numerous product reviews from people speaking highly of your products, I recently decided to purchase some Victron Products for my own project (Smart Shunt, MPPT Charger, and USB comms cable) ... While these products work as specified, I am extremely disappointed with your methods of assembly whereby none of these products can be inspected and or repaired/modified without destroying their packaging. Understand that while most people leave products as is, there are some of us that won't be stopped by this practice ... we need to stop making products that end up in the landfill. Moreover, anyone that wants to reverse engineer your products are NOT going to be stopped by this unnecessary assembly practice. Please reconsider packaging your products for ease of service and or mechanical modification ... A prime example is the comms connector for the USB cable on the SMART 75/10 MPPT charger ... this connecter is impossible to change or repair without destroying the product case ... would also highly recommend including an internal block and level diagram in your manuals especially for these smart chargers.
