Problems with converting to Presta Valves
Used for 1 week or less
The pump works reasonably well although I have struggled to get beyond 90psi. Problems in other reviews with converting to Presta valves is because the orientation of valve part 1 on the hanging ticket is back to front!! If you look at he thumbnail photo on the product on the website it shows the correct orientation. A few happy hours figuring this out! Come on Decathlon "retail is detail"!!
Unclear
Used for 1 week or less
Says it can support both types of valves. Very difficult to first find the adaptor within the pump, then actually adapt it. Really don't understand why they couldn't put decent instructions on it.
Response of the brand
I agree with you that flipping the innards or a valve is time consuming. What we often recommend is to obtain a brass presta adapter which costs mere pennies which can be used for presta valves negating the need to constantly dismantle the valve.

Does the job.
Used for 2 to 8 weeks
Fits presta and Schrader valves but fiddly to swap adaptor around.instructions not very clear. But does the job.
Listen to the reviews - valve swapping unclear
Used for 1 week or less
It is really not obvious how to take the valve apart, reverse it, and use for the presta valve, and you can see the reviews below to prove it. It took a btwin video online to actually figure out that the inside part could be pried out.
Not useful for Presta valves
Used for 1 week or less
I bought this to use on my road bike and saw on the label in store that it supports both types of valves. Got it home and there is no adapter and no swapping function. In theory it can support both but only if you purchase extras. How good it is I don't know, but not overly happy being caught out by the store
