Even though there aren't really any other options for 28mm WW1 Russians, this kit is extremely well-detailed, dynamic, and is a great value for the price. These guys look phenomenal when you get them done, and they're detailed without being too busy, which means they paint up to tabletop standard very quickly.
That said, there are some issues with the build and the sprues. For one, the kit does not come with instructions, and not all the arm options fit properly on all the torso options. The kneeling figure in particular can fit maybe two of the nine cross-torso arm sets without liberal use of sprue goo or greenstuff, so expect to use the "pointing arm" and pistol arm on this guy a lot.
The sprues themselves certainly have some... choices. Unlike the other kits in this line, you can't really use this box to make specialists, as you get no machineguns or carbines, and your options outside of Mosin-Nagants on each sprue are limited to a single Arisaka, a C96 Mauser (with no real space on the arm to attach the holster-stock), a Nagant 1895 revolver, two officer's sabres (one sheathed, one wielded), and a single arm holding a grenade. As such, the kit is great for line infantry, but you'll have to look at other options or kitbash with the other kits in this line to make specialist. Even making unarmed models for conscript fireteams is a bit difficult, as there are only two sets of left and right arms on each sprue that can be assembled without weapons, and they can look a bit awkward if not properly combined.
The head options are an odd choice as well. The peaked caps are great, both the open-faced and gas-masked ones, and add a lot of character to the kit. The kit also comes with Budenovka hats for making RCW Red Russians, which is at least somewhat interesting; and a full suite of open-faced and gas-masked Adrian helmets, which is an oddball choice considering these were barely used by the Russian army in WW1 at all. This is great for anyone who wants to recreate one of a handful of battles in 1916, but I would have preferred that the space on this sprue for helmets be given over to more specialist options or trench weapons instead.
Once you finally get the hang of putting these guys together (the first sprue is definitely the hardest), they're actually pretty fun and relaxing to assemble, and they look good painted up without too much extra effort. I definitely recommend them, though with the caveat that they may be a bit overwhelming for an entry-level hobbyist and that you'll probably have to track down some other options to fill out your army properly.
