I bought this tent at the beginning of the summer, have now spent the best part of a month with it, and think I have enough experience with it to provide some opinions. I've worn out a lot of tents over the course of my life, starting with a Saunders Jetpacker (remember those?!). I also have a Vaude Taurus 2-person tent, bought during happier, more optimistic times and now pretty much a summer tent (good tent, and one that withstood a lot of weather; lousy customer service) and the Terra Nova Voyager 2 I bought to replace it (great, but better suited to trekking with a companion, which I no longer have).
So, the Terra Nova Laser Competition 1.
First, some specs.
This is a one-person tent, weighing just under a kilo, rated for three-season use. TN claim that it can sleep two, but I would say that you would need to love each other deeply for this to be viable. It has a hydrostatic head of 5000mm. The 5-minute pitching estimate from TN is, in my experience, pretty accurate, although I've done it in less in bad weather/predation (midge!) conditions. It retails for something in the region of £280 (some retailers charge considerably more: be cautious!).
Aside from some odd days here and there, I have carried it from Pitlochry to Forres via the Cairngorms and the Dava Way (in June; 5 nights), the entire length of the Outer Hebrides (in July; 15 nights counting an overnight in a backpackers and the return) and from Milngavie to Pitlochry via the Rob Roy Way (in November; 5 nights, allowing one night under a roof in Callander).
I like this tent for its tiny ground profile (100cm high, 220 cm long, 143cm wide). Its small packed size means you can sort your rucksack before you take the tent down. I carry it strapped to the outside of the rucksack. I've pitched it on woodbanks and in ravines that would simply not have been able to accommodate the Voyager.

I did have the tent pitched for shelter in this ravine on the north end of Lewis. There was no way it would have accommodated the Voyager.
There are two aspects to the other side of that coin. One is that some might consider it downright claustrophobic. I'm pretty short (164cm), and anyone much taller than me would have their head squeezed right up against the very low (40cm) end of the tent. The other problem is the huge condensation profile. There are ventilation panels (with midge-netting) at each end but, unless it's breezy, even with these vents open condensation builds up very fast. My experience is that the drip point is directly above your face. I've stayed considerably dryer on wet, breezy nights than on humid still ones.
A reasonable porch area means that I've been able to stow the rucksack while using the natural gas stove under shelter, although I wouldn't want to risk doing the initial priming of my liquid-fuel stove here.
Unlike the Voyager, this tent pitches outer first, so can be pitched in one go.
The tent comes with three poles, of which the two end ones can be left in place, which assists with rolling. The end guy lines present a surmountable problem. Plastic clips seem to be intended to hold the guys taught, but they have a tendency to slip in any more than a light breeze, allowing the inner and outer to touch, with inevitable consequences. My solution to this has been to tighten the line, check the skins are not in contact, then tie the line off round the peg. At that point, the rain stays out.
The centre arch cannot be seam-sealed, so a sleeve protects this from rain. Three tie points connect this to the tent, and it's then guyed out. These tie points are definitely weak, and I've had to repair the sleeve once already.
With all the pegs in place, the tent is pretty stable in even a high wind, as I found one night at the southern entrance to the Lairig Ghru. One peg did pull out in a strong gust, but it was poorly inserted in what felt like glacial till. The tent coped with this – not well, but it did stay up.

In conclusion, this is a good tent for one person while hiking. It is not a great tent, the main problem being condensation. There probably are better one-person tents on the market, with similar ground profiles and greater storm resistance, but they're in a much higher price bracket. I also think that low-level hiking in November is probably a limit. It did stand up to some unpleasant conditions in the Cairngorms, but it's not bombproof.
