The only reason this telescope might be labeled an introductory scope is that it will "introduce" inadequacies you will want to avoid next time. This package is of rather inferior construction and mediocre mechanics--a lot of plastic. I would expect the gambit of similarly priced competitors' scopes to be no better.
The principal deficiency is the shaky mount. When you need to adjust focus, reposition an image, change an eyepiece, or if the breeze rises, the scope shudders badly. By the time it finally settles down some, the image will often have moved out of the view. The focuser shifts position obliquely when adjusting focus back and forth which also shifts the viewed image. This accentuates the shaking problem because one must necessarily spend more time handling the scope to accommodate. The poor mount will sap much enjoyment out of viewing objects in the night sky.
The 90° erecting prism works okay as does the red dot finder (provided you know where in the sky to aim it). Given the price, these are satisfactory.
The package came with 20mm, 10mm and 4mm oculars, and a 3x barlow. The 20 and 10mm eyepieces provide a fair image (again considering the price), though there is chromatic aberration (a rainbow affect). Astronomically, the included 4mm isn't suited for this scope, and the 3x barlow is about useless.
Bright stars do not resolve well, but I was able to get decent views of the moon and degraded images of the planets (it was hard to tell whether the planets were truly in focus because of the constant shuddering.) I was also able to detect the Great Nebula in Orion, M42.
With modifications to the mount and better eyepieces this might be an okay telescope for viewing the moon and planets. You will have to weigh how much you want to invest improving this small aperture model as opposed to buying an instrument of higher quality to begin with.
