OPINION

BARRY, Circuit Judge.

Plaintiffs Joseph and Carol Scrofani brought suit against Stihl, Inc. and Stihl Northeast (collectively “Stihl”), in addition to York-Hunter, Inc., for various torts under New Jersey law. The suit arose from burn injuries that Mr. Scrofani sustained at a York-Hunter construction site on August 4,1997, while he was using a gasoline-powered saw that was manufactured and sold by Stihl. The Court granted Stihl’s motion to exclude as unreliable the testimony of plaintiffs’ expert witness. It also denied plaintiffs’ motion pursuant to Federal Rule of Evidence 104 for a *Daubert*hearing to assess their expert’s qualifications. The Court then granted Stihl and York-Hunter’s motions for summary judgment. Plaintiffs filed a timely notice of appeal, but subsequently settled with York-Hunter. They now challenge the exclusion of the testimony of their expert, the denial of a *Daubert*hearing, and the grant of summary judgment to Stihl. We have jurisdiction pursuant to 28 U.S.C. § 1291. For the reasons that follow, we will affirm.1

Because the parties are familiar with the underlying facts, we need not recite them in detail here. Plaintiffs argue that Stihl is hable for the manufacturing and sale of the Stihl Model TS-350 cut-off saw (“TS-350 saw”) in or around 1994. Specifically, they assert that Mr. Scrofani was injured by the TS-350 saw because it (1) was defectively designed and (2) contained inadequate warnings. To prove these theories of liability, plaintiffs relied almost exclusively on the opinions of expert witness Russell Fote, which, as noted, were excluded from evidence. The Supreme Court has emphasized that “the trial judge must have considerable leeway in deciding ... whether particular expert testimony is reliable.” *Kumho Tire Co., Ltd. v. Carmichael,*526 U.S. 137, 152, 119 S.Ct. 1167, 143 L.Ed.2d 238 (1999). We review the Court’s decision to exclude expert testimony for abuse of discretion. *United States v. Mathis,*264 F.3d 321, 335 (3d Cir.2001).

To be admissible, expert testimony must “not only [be] relevant, but reliable.” *Daubert v. Merrell Dow Pharmaceuticals, Inc.,*509 U.S. 579, 589, 113 S.Ct. 2786, 125 *562L.Ed.2d 469 (1993). Even if a witness is qualified as an expert, he or she may only testify if:

> (1) the testimony is based upon sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.

Fed.R.Evid. 702. Here, it is abundantly clear that what Fote had to say as to both the defective design and inadequate warning claims was not reliable and that the Court did not abuse its discretion in excluding Fote’s testimony. As the Court observed with respect to design defect, Fote’s opinions were not based upon sufficient data, nor were they the product of rehable methods applied to the facts in a rehable manner; indeed, Fote “employed absolutely no methodology at all,” merely setting forth “a series of unsubstantiated opinions.” As for the failure to warn, the Court concluded that Forte’s report “gave no clue” as to how he reached the “bald conclusion” he reached and “more than suggests” that he did not even read the warnings which accompany the TS-350 saw which, in any event, were the same warnings Fote described as necessary.

Moving to the next issue, plaintiffs claim that a *Daubert*hearing would have estabhshed Fote’s qualifications as an expert. Even if the Court had concluded that Fote was a qualified expert, however, and it did not find that he was not, it would have been proper to exclude the evidence he proffered because, as noted above, he failed to base his conclusions on sufficient data and his methodologies were either nonexistent or wholly unreliable. Accordingly, the Court did not err in refusing to grant plaintiffs’ request for *Daubert*hearing. *Oddi v. Ford Motor Co.,*234 F.3d 136, 153-54 (3d Cir.2000).

Finally, plaintiffs argue that the Court erred when it granted summary judgment in favor of Stihl on the defective design and inadequate warning claims. We exercise plenary review over a grant of summary judgment. *Pacitti v. Macy’s,*193 F.3d 766, 772 (3d Cir.1999). Under the New Jersey Products Liability Act, a manufacturer or seller may be held strictly liable for harms caused by a product where (1) the product suffered a manufacturing defect, (2) the product was defectively designed, or (3) the product warnings were inadequate. N.J.S.A. 2A.-58C-2; *Roberts v. Rich Foods, Inc.,*139 N.J. 365, 375, 654 A.2d 1365 (1995). To establish liability, a plaintiff must prove by a “preponderance of the evidence that the product causing the harm was not reasonably fit, suitable or safe for its intended purpose.” N.J.S.A. 2A:58C-2.

Plaintiffs assert that the fuel cap design of the TS-350 saw was defective, causing fuel leakage which combusted and seriously burned Mr. Scrofani. To establish a design defect claim, a plaintiff “must prove either that the product’s risks outweighed its utility or that the product could have been designed in an alternative manner so as to minimize or eliminate the risk of harm.” *Lewis v. American Cyanamid Co.,*155 N.J. 544, 570, 715 A.2d 967 (1998). Plaintiffs must also prove that such an alternative design was “practical and feasible.” *Id.*at 571, 715 A.2d 967. Plaintiffs utterly failed to meet their burden, as the Court correctly found, and do not seriously press this claim before us.

Summary judgment for Stihl was also proper on plaintiffs’ inadequate warning claim. “A duty to warn is consonant with a manufacturer’s broader duty to place in the stream of commerce only products that are reasonably safe.” *Coffman v. Keene Corp.,*133 N.J. 581, 598, 628 A.2d 710 (1993). To establish his claim, Mr. Scrofani was required not only to prove that the warnings were inadequate, *563but that they were the proximate cause of his injury. When evaluating causation, it is presumed that an injured party “would have followed an adequate warning had one been provided.” *Id.*at 603, 628 A.2d 710. The defendant may rebut this presumption, however, by producing “evidence that such a warning would not have been heeded.” *Id.*

Even if the existing TS-350 saw warnings were inadequate,2 Stihl submitted ample evidence to rebut the presumption that Mr. Scrofani would have heeded an adequate warning. Scrofani testified that, at the moment of his accident, he was well aware of the risks of using the TS-350 saw and that he was very familiar with the information in the product manual. Nevertheless, he acted in direct contravention of numerous warnings contained therein. This disregard of existing warnings demonstrates that Scrofani would have ignored the most perfect of warnings. “Evidence that a plaintiff would have disregarded an adequate warning ... tend[s] to demonstrate that the plaintiffs conduct, rather than the absence of a warning, was the cause in fact of the resultant injury.” *Coffman,*133 N.J. at 604, 628 A.2d 710. Because plaintiffs submitted no evidence indicating that a different warning would have prevented this accident, the grant of summary judgment in favor of Stihl was proper.

For the foregoing reasons, we will affirm.

1

. The parties consented to a trial before Magistrate Judge Stanley R. Chesler pursuant to Fed. R. Civ. P. 73(a), in accordance with 28 U.S.C. § 636. Magistrate Judge Chesler entered a final judgment which is directly ap-pealable to this court pursuant to Fed. R. Civ. P. 73(c), in accordance with 28 U.S.C. § 636(c)(3).

2

. Plaintiffs claim that the warnings in the 1994 TS-350 saw manual did not provide the required "directions, communications, and information” to make the TS-350 saw safe, asisde from Fote’s unsupported opinion, the only proof that plaintiffs offered was a 1996 manual from the same TS-350 saw which, according to them, gave far more specific warnings than the 1994 manual. Contrary to plaintiff's asssertion, the relevant warnings in the 1996 manual are neither more comprehensive nor more specific. In fact, they are virtually identical to the relevant warnings in the 1994 manual, which are extensive and explicitly warn about precise dangers Scofani encountered when using the saw.
