CPSdrone Avis 

I got the CPS5 course after looking at the free intro. The instructions are clear, the course is being actively updated if they find improvements and there's a discord server to ask your questions. I'm still building the drone, but am looking forward to taking it for a dive.

Fantastic. Better than I expected, these folks are super. Couldn’t recommend them and the courses enough.

This guys do what they do with a passion. Support them.

I had some issues getting a hold of the team many months ago with the first cps5. To which I gave up but with the release of the cps3. I tried again and could not reach them. Once I posted this review they found my emails.

This guys are very skilled and give what promised. Haven't build the drone for now, but will do.

This is wonderful! I (55+ yr IT guy) went through the same journey 5 years ago (never got 3d printing waterproof tough and build a cnc instead to solve that problem). These guys clearly know what they are doing and have many inventive solutions to the little problems encountered along the way (e.g. the auto-on by connecting the cable!). They persevered and continued after their first prototypes and are now truly building a business out of it. The course is truly worth it (the BOM alone will save you from buying so much material that turns out to be wrong to gain back the price of their course). Mind that you'll need to spend a lot more to actually build the drone but I know from experience that it will be hard to do cheaper than what they are proposing. If you love DIY this is a joy!

Awesome course so much information and the guys are truly funny, my 6 year old son is also loving the courses

A very thoughtfully assembled course!

Well thought out and very thorough

I have just started this project.
everything to date has been amazing! so pound to be part of this group.
Looking forward to playing in the deep water soon :)

Love attitude and project. The guys are fantastic

A great course, perfectly designed, with lot's of details on the construction process as well as side information about other possible solutions. All files are easily printable and slicing for different machines is nicely explained. Very well done!

Just started to build the ROV. Very detailed instructions.

Experience Great

The way all the chapters are organized is awesome. The details of whole procedure to build CPS 5 are very good even a person with very less experience on hands can make it.
I am satisfied with this course and would say that it is worth buying it if you want to make CPS 5 an underwater drone

These guys have put a lot of thought and work into this Submarine project. They have saved me a lot of time (which I have limited amounts of) and frustration. It will allow me to concentrate on developing it further to meet my requirements.

excellent course very well done with a responsive team. I would just like a complete electrical diagram of the interconnections between the different elements.

Wonderful course with thorough steps and instructions. Top notch DIY with everything promised and more!
