Fun and easy to follow. There are really small pieces so please be cautious with smaller children. This was for my eight year old and he did great. He had so much fun putting it together even though his little fingers hurt afterward.
Well made, all pieces were there. Held together great and it even worked well. It was a little hard to pull on the trigger for the bullet to shoot out but with a little me strength and some help it worked. It was awesome! (My son's words)
I recommend it for all ages. It's a fun way to spend time with your kids. Building together helps for a greater bond.

I purchased this for my older nephew as a Christmas gift. He's in his very early teen years, and he loves building stuff like K'nex and Legos (but really, are we ever too old to play with things such as these? Last year I sent him a K'nex motorized robot and it was the one gift he gravitated to, mostly. I figured this one to be perfect since he lives in a house with a large amount of property, and it's also something he can build AND play with afterward, as opposed to building something that stands stagnant and has no purpose besides building it (think model car). To the child inside of me, this is a great toy.

Definitely not child-friendly to put together unless you're above the age of 12. Once it's put together it's very hard to keep it together this constantly losing little pieces. But it does shoot bullets a long ways and my boys thought it looked really cool

Super fun toy!!!!! Since there are 2 units, it's great for kids to do together or for a singles to do with a parent. And what a cool reward..... After you successfully build the blaster you then get to have a whole new experience, War! Beware though, it packs a strong punch.

Als ich die K'nex K Force Blaster Serie vor 2 Tagen mehr durch zufall entdeckt hatte, war ich ja doch erst ein wenig Irritiert. Ein Blaster, der durch K'nex Teilen zusammengesetzt wird? Hält das? Hat der überhaupt einen Nennenswerten wert für mich alten Nerf und Buzzbee Fan? Aber da der oben genannte Blaster preislich gesehen ok war, dachte ich, warum nicht? Also bestellt, und nächsten Tag war er da. Als allererstes sei gesagt, der Aufbau war eine Zeitreise zurück in die Vergangenheit. Einfach nur Toll. Gut, ich habe knapp 1/2 Std. gebraucht, aber psssssst.

Als der Blaster fertig war, hatte ich dann erst mal einen Schusstest gemacht mit den 5 Darts, die dabei sind. Und die Reichweite war fast erschreckend gut, auf jeden Fall Nerf Qualität. Zu Laden geht der Blaster durch einen Spannhebel direkt hinten, einfach ziehen, einrasten lassen und los gehts. Alte Blasterhasen werden jetzt natürlich sofort an die Firestrike oder ähnliche denken. Ein wenig störend werden wahrscheinlich viele finden, das der Spannhebel ziemlich nah am Blaster sitzt, was das spannen etwas behindert und das der Abzug nur aus einer Stange besteht, ist etwas wackelig. Ich finde das sollte man bei einem Selbstbau Blaster erwarten können, aber zu meckern hat ja immer jemand was.

Die Darts sind übrigens Nerf Kompatibel. Sehr stabil, und haben eine wirklich Softe Spitze. Die Flugleistung kann sich sehen lassen.

Alles zusammen ist dieser Blaster schon genial. Ist mal was anderes, den Blaster mal selbst aufzubauen, und nicht immer nur Auspacken, laden und los gehts. Bei mir sitzen alle Teile sehr stabil aneinander, es wird sich so schnell nichts lösen. Aber ob der Blaster wirklich Combat tauglich ist, wage ich zu bezweifeln. Aber auf einer Geburtagsparty ob drin oder im Garten bestimmt der Renner.

Ich persönlich lasse es mit der Serie K Force bei dem Blaster gut sein, war auch nur Neugierig, aber ich denke gerade für Kinder ist das schon eine Geniale Sache.

Dieses System hat meinen Sohn (12 Jahre) überzeugt. Als erstes hat er sich voller Begeisterung mit dem Bausatz auseinandergesetzt - das hat schon mal seine Vorfreude fürs Schießen gesteigert. Ca. nach 30 Minuten war die kleine Waffe zusammengebaut. Und der erste Schuß wurde abgesetzt. SUPER! Mein Sohn ist begeistert.
Ich war etwas skeptisch (habe beim Zusammenbau zugesehen), ob das auch alles hält -> JA, es hält und funktioniert bisher gut.

I purchased this for a child. I think the instructions said easy to assemble. Haha. Took me ages putting it together and had pieces left over that I couldn't work out where they went. Maybe it's how I put it together, but the trigger comes detached quite a lot. It's not as easy to use as a Nerf gun, but it still provided lots of entertainment.
