This is the first scroll saw I have owned.  It waited 6 months after I purchased this saw To writhe a review.  I read many reviews and looked long and hard before making the decision to purchase this saw.  I had seen various saws at Lowes at close out and their prices were tempting but I kept on reading and reviewing.  Finally an Amazon sale tipped me to this one.  Since I have had it I have used it constantly.  I have let my grandson use it so it has seen much use.  The blade change and tightning system is easy with no problems .  My 9 year old grandson has no problem changing or installing blades.  The table depth is great and I am glad I didn't buy a cheaper unit at Lowes on sale because I can now see the advantage of the deep throat of the saw.
