Question: Can adults use this ...
Document: not really good racket for 8 yrs old.may be good racquet but is not the best.I brought this racket and prince with handle size 0. my son love the price. so I did not even open it , just returned it.
We just moved to a community with a tennis court. As not having played tennis I wish I would have done more research and what sizes to get my children. This one fits, but it was only by luck! Make sure you check to make sure the size is age appropriate before ordering!
Unfortunately, I don't think the racquet was strung well and I had to have it re-strung within 4 months of purchase...and the price for stringing was the same price as the racquet itself.Four stars for weight and relatively rapid replacement.Three stars for requiring rapid replacement and restringing.
These balls are great. It's tennis balls so not much out of the realm of what I expected but they work!
Purchased this through Amazon Prime for my 6 1/2 year old whose tennis coach said he needed to upsize to a 25&#34; racquet. The racquet started rattling right out of the box. I was able to exchange it for a new one thanks to Amazon Prime, but my son had to have one additional lesson with his outgrown racquet until the replacement arrived. He did quite nicely with it and commented on how light it was compared to his old one.
My four sons 10 yrs and younger just started enjoying the game of tennis. These racquets are light and well made. I was thrilled with the low price for such a great brand-name product!
Its just perfect, sturdy, and I couldn't ask for a better price! I have recommended this product to many friends who too enjoy it!
I received it very fast, well wrapped and in really nice conditions. The racquet is light and very easy to play. Nice product!
I love the way they handle and the comfort. Only thing is I didn't know that the net part of it was so strong so needless to say I hit the first ball over the fence so I had to start hitting it a little softer, but everything is fine and dandy. Thanks
I bought this for my 11 y/o who I just started teaching tennis to. It is lightweight with a good surface area and comfortable grip. I bought an extra in case a friend wanted to join in. At this price for the brand, it is well worth the money.
Answer: no
