large footprint can make it harder to find a suitable camp site to pitch - especially the 2P version
for a good pitch you need fairly level ground and the fly must be pegged out as close to a rectangle shape as possible with 90deg angled corners
magnetic fly door holder is not strong enough to secure the door flap open in strong wind - bring a clamp
the elastic tie for the inner door flap is fiddly especially if wearing gloves - bring a clamp
you do need to supply your own stakes and guy ropes - make sure the stakes are strong enough!
the storage pockets are small compared to most other tents and not well supported but will still do a reasonable job
the asymmetric inner tent geometry for 2P means that if you both sleep the same orientation, one of you will get much less head room - solved by sleeping head to tail
inner tent corners can be fiddly to attach to the fly, especially from the inside - consider adding a carabiner
you need two hands to use the inner door zips unless you have it perfectly pitched
in heavy rain or hail, the inner can get muddy at the bottom from splashes if the fly is not touching the ground as it tends to sit above the ground unless pegged down in the centres as well as the corners
the optional footprint can be hard to orient to the inner tent - best placed after the inner tent is set up
when packing up wet, it is probably best to pack the inner tent separately to the fly which is a bit more work
general issues as with all non-freestanding tents:
can't move the tent once pitched unless fully taken down
stability is absolutely dependent upon security of the pegs - if only use the 4 corner pegs, it will collapse if one becomes loose
can't tip it upside down to dry the bottom of the floor before packing up - you will need to pack it wet or hang it up somewhere - use the optional ground sheet and leave it attached to the fly when packing up - they will both be wet anyway (pack the inner tent separately)
